Title: Modulator for light emitting semiconductor device - has circuit generating pulses which coincide with the transition of modulating wave
IPC: H04B10/50
Filed: 1976-02-13
Abstract: Circuit for direct modulation of a light emitting semiconductor device generating a modulated light beam which contains a source of controlling current. The modulator contains a pair of input terminals to receive the modulating signal with a specific wave form. A pair of transistors with common emitter resistor functions of the pulse forming amplifier for the input signal. The input signal is fed to the base of an emitter follower. This output is fed to the base of the transistor on one side and to a Zener diode on the other side which is connected to the base of a transistor. The output transistor is connected in series to a light emitting diode and a resistance. The output transistor functions as the source for the controlling current. The current pulses generated coincide with the transition points of the modulator.

Title: Converter for LF oscillations into acoustic vibrations - has capacitor loudspeaker connected to coil centre tap with ends connected via switches
IPC: H04R3/00
Filed: 1976-08-30
Abstract: The device is used to convert low frequency electrical oscillations via a reactive transducer into acoustic vibrations. The transducer is part of a tuned vibration circuit. The oscillating circuit consists of a capacitor (1) which functions as a loud speaker. One side is connected to the centre tap (2) of a coil (3). The ends of the coil sections (4, 5) are connected to the loudspeaker via switches (6, 7). A l.f. oscillation approx. equal to the resonance frequency is fed to the circuit which will use electronic switches. The switches will operate in anti-phase and in synchronism with the resonant frequency at a number of instances when the energy content of the transducer is at zero. The high frequency oscillation is modulated by the l.f. oscillation.

IPC: G02B6/126
Filed: 1991-11-01
Abstract: The invention relates to an integrated optical component which comprises an adjustable Mach-Zehnder interferometer. The waveguide structure of the component is fabricated on the basis of polable unpoled material, the material in one (2) of the branches (2, 3) of the MZ interferometer being poled in a certain area (7). In the case of maximum poling in advance, the degree of poling of the poled material can subsequently be adjusted under conditions of accelerated thermal relaxation. Advantage: the component can first be fabricated, as far as its structure is concerned, using fabrication techniques which are standard for the selected material without additional attention to correct sizing, after which the interferometer section can then be adjusted in a simple manner to the optical pathlength differences required for the specific function of the component. As an example, a passive polarisation splitter is described. <IMAGE>
