Abstract: A vertical cavity surface emitting laser (VCSEL) (10) having a tunnel junction (14) and emitting long wavelength light (i.e., 1200 to 1800 nanometers, though it is contemplated that the structures and techniques are applicable to other wavelength VCSELs). The tunnel junction (14) may be isolated with an implant (21) down into the top mirror (15) through the tunnel junction (14) and p-layer (13) and a trench (19) around the VCSEL (10) down to at least past the tunnel junction (14). The trench may result in reduced capacitance and D.C.  isolation of the tunnel junction (14). The implant (21) is performed after the trench (19) is made. Some of the implant (21) may enter the bottom of the trench (19) into the bottom mirror (11) for some further isolation for the tunnel junction (14) of the VCSEL (10). Further isolation and some current confinement may be provided with lateral oxidation (23) of a layer (13) below the tunnel junction (14). Internal trenches (33) may be made from the top of the VCSEL (10) vertically down to the oxidizable layer (13) below the tunnel junction (14). Oxidation of that layer via these trenches (33) may provide further isolation of the tunnel junction (14). Also, a bonding pad (29) connected to a contact (16) on the VCSEL (10) with a bridge (31) may have an open trench (19) about their periphery for their isolation. Internal trenches (34, 35) may be placed on the pad (29) and its bridge (31) that go down vertically to the oxidizable layer (13). Oxidation via these trenches (34, 35) may provide further isolation for the pad (29) and bridge (31) if the latter is present.

Title: Clock and data recovery phase-locked loop and high-speed phase detector architecture
Inventor: BRUNN BRIAN T
IPC: H03L7/091
Filed: 2004-01-16
Abstract: A clock recovery circuit and a high speed phase detector circuit that operate at a clock speed equal to one-half the input data rate (i.e., a half-rate clock) are presented. The clock recovery circuit uses dual input latches to sample the incoming serial data an both the rising edge and falling edge of a half-rate clock signal to provide equivalent full data rate clock recovery.  The clock recovery circuit functions to maintain the half-rate clock transitions in the center of the incoming serial data bits. The clock recovery circuit includes a phase detector, charge pump, controlled oscillation module and a feedback module. The phase detector produces information on the phase and data transitions in the incoming data signal to the charge pump.  Generally, the circuit is delay insensitive and receives phase and transition information staggered relative to each other. The high speed phase detector circuit provides phase information and transition information from incoming serial data. The high speed phase detector circuit samples the incoming serial data on both the rising edge and falling edge of the half-rate clock to provide equivalent full high speed data rate sampling. The high speed phase detector circuit generates a delay between the phase information and the transition information. The phase information is produced in a first bit period and the transition information is produced in a second bit period relative to the first bit period.

Abstract: A method and apparatus for determining a vertical and horizontal (X-Y) target shot position on a Liquid Crystal or Plasma display screen may be adapted to connect to commercially available video game console systems. Upon a trigger event from a light gun when it is pointed at the target shot position, a blanking signal renders the monitor black during a first vertical refresh cycle. During a second vertical refresh cycle, the voltage to each of the red, blue and green channels is increased in three separate screen sections to create a display split between the three colours. The light gun is adapted to be capable of separately detecting a blue, red or green light pulse and the X-Y  coordinates of the target shot position is determined on the basis of the colour detected by the light gun and the length of time which elapses between the start of the second vertical refresh cycle and the detection of the red, blue or green light pulse.
