Title: Tunable fabry-perot filters and lasers utilizing feedback to reduce frequency noise
Inventor: TUCKER RODNEY S
IPC: G02B7/182
Filed: 2001-01-22
Abstract: A tunable optical cavity constructed from a fixed mirror[214] and a movable mirror.
The fixed mirror[214] is attached to a substrate[203] having a first electrically conducting
surface. A support member[216] having the moveable mirror[213] supported thereon and
having a second electrically conducting surface, is suspended above the substrate[203]. A
circuit applies an electrical potential between the first and second electrically conducting
surfaces thereby adjusting the distance between the fixed and movable mirrors. The fixed
mirror[214] and the moveable mirror[213] are positioned such that the mirrors form the
opposite ends of the optical cavity. The distance between the fixed mirror[214] and the
moveable mirror[213] is a function of the applied electrical potential. The thermally induced
vibrations are reduced by utilizing an electrical feedback circuit that measures the distance
between the mirrors. The feedback circuit dynamically changes the potential between the
substrate[203] and the support member[216] so as to reduce fluctuations in the cavity
resonance frequency. The instantaneous cavity resonance frequency can be measured by
comparing the cavity resonance frequency with a standard optical signal, or by using a circuit
for measuring capacitative coupling between the support member[216] and the
substrate[203]. The feedback circuit varies the potential between the substrate[203] and the
support member[216] so as to reduce the fluctuations in said measured cavity resonance
frequency or the capacitance. The optical cavity of the present invention can be utilized in
constructing a tunable laser by including an active layer[355] for amplifying light trapped in
the cavity. In the case of a tunable laser, the thermally induced fluctuations can be reduced
by including an interferometer[360] or other frequency-selective device to determine the
instantaneous wavelength of the light from the laser. An electrical feedback circuit[375]
varies the potential between the substrate[203] and the support member[216] so as to
maintain the measured instantaneous wavelength at a specified value.

Abstract: According to the display device of the present
invention, counter electrodes are formed in stripes at a
position facing pixel electrodes, with a polymer dispersion
liquid crystal held between the counter electrodes and pixel
electrodes. When a positive-polarity signal is to be
impressed to a pixel electrode, a negative-polarity voltage
is fed to the counter electrode. On the other hand, when a
negative-polarity signal is to be impressed to a pixel
electrode, a positive-polarity voltage is added to the counter
electrode. In this impressing manner of voltages, a high
voltage can be applied to the polymer dispersion liquid
crystal layer on the pixel electrodes, so that the liquid
crystal layer is turned into the transmitting state even if
it is thick. Accordingly, the scattering efficiency is
improved and images are displayed with high contrast as the
liquid crystal layer can be made thick. If the thick
transparent substrate is bonded to the counter substrate
having the counter electrodes thereon, the light scattered at
the liquid crystal layer is reflected by the counter substrate
and returned back to the liquid crystal layer, thus eliminating
the light to be scattered again. The display contrast is
improved. When the display device is utilized as a light
valve of a projection-type display apparatus, it realizes a

Abstract: A fault on the generator (12) can be detected with the
use of a simple arrangement. The output of the generator
(12) which has multi-phase winding and is driven by an engine
(11) is rectified and then converted by an inverter (133)
into an alternating current at the frequency of a system
before interconnected to the source of the system (14).
After the engine (11) is started, the direct current voltage
Vdc is monitored with a first fault monitor (40). When the
direct current voltage Vdc rises up to a predetermined level,
a connector relay (135) is closed. As the output of the
inverter (133) is increased, the interconnection with the
system source (14) is enabled. After the interconnection,
the direct current voltage and the output of the inverter
(133) are monitored with a second fault monitor (43). If
the direct current voltage drops down to below the
predetermined level before the output of the inverter (133)
reaches a rated level, the canceling and re-interconnection
is repeated. Then, when the direct current voltage remains
below the predetermined level after the re-interconnection,
it is judged that the generator (12) has a fault such as
a line breakage in the windings disconnection.

semiconductor wafer by obtaining a frequency measurement
result highly accurately in a short period of time. A
device (FC) for measuring the frequency of a measured signal
(Vin) comprises a counting section including a number i
of n-nary counters (1-i), a time reference circuit (13) which
outputs a time reference signal (T), whose duration is t,
every time interval p, and a number I of gate circuits (G1
to Gi) whose outputs are connected to the inputs of the
n-nary counters (1-i). The gate circuits receive the
measured signal (Vin) at a first input and receive the time
reference signal (T) at time intervals p at a second input.
With this structure, the counting section supplies the
frequency measured result of the measured signal (Vin) every
time interval p. 
     Further, the present invention provides an eddy
current sensor capable of stable operation for
accurately detecting a polishing end point. The eddy
current sensor detects the thickness of a conductive film
from a change in an eddy current loss generated in the
conductive film. The eddy current sensor comprises a
sensor coil for generating an eddy current in the
conductive film, and an active element unit connected to
the sensor coil for oscillating a variable frequency
corresponding to the eddy current loss. The sensor coil
and active element unit are integrated to form the eddy
current sensor. Alternatively, the eddy current sensor
comprises a sensor coil for generating an eddy current in
the conductive film, and a detector for detecting a change
in the thickness of the conductive film from a change in a
resistance component (R) in an impedance formed by the
sensor coil and conductive film.

Abstract: An optical switch includes a saturable absorber. Coupled to the saturable
absorber is an input waveguide, an output waveguide, and a control beam waveguide.
In the absence of light input to the control beam waveguide, the saturable absorber
prevents an input signal on the input waveguide from passing through and being output
on the output waveguide, thus placing the switch in an "off" state. In the presence of
light input to the control beam waveguide and incident of the saturable absorber, the
saturable absorber allows the input signal to pass through and be output on the output
waveguide, thus placing the switch in an "on" state.
