Title: Arrangements for reducing wavelength sensitivity in prism-coupled soi-based optical systems
Inventor: GHIRON MARGARET
IPC: G02B6/34
Filed: 2004-04-28
Abstract: An optical coupling system for use with multiple wavelength optical signals provides improved coupling efficiency between a free-space optical beam and a relatively thin, surface layer of an SOI structure ("SOI layer"), allowing for sufficient coupling efficiency (greater than 50%) over a predetermined wavelength range. An evanescent coupling layer, disposed between a coupling prism and an SOI layer, is particularly configured to improve the coupling efficiency. In one embodiment, the thickness of the evanescent layer is reduced below an optimum value for a single wavelength, the reduced thickness improving coupling efficiency over a predetermined wavelength range around a defined center wavelength. Alternatively, a tapered thickness evanescent coupling layer may be used to improve coupling efficiency (or a combination of reduced thickness and tapered configuration). Optical beam steering can be combined with a modified evanescent coupling layer to control the input beam launch angle and further improve coupling efficiency.

Title: Ultra-low power programmable timer and low voltage detection circuits
Inventor: LOURENS RUAN
IPC: G01R31/40
Filed: 2004-06-03
Abstract: An Ultra-low power voltage detection circuit is implemented in a digital integrated circuit to device to provide a basic timer, programmable timer and programmable low voltage detection (PLVD) using a single connection of the digital integrated circuit device and a passive component(s) external to the digital integrated circuit device. An internal low current source may be enabled so as to discharge an external timing capacitor connected to the output connection, thus eliminating the need for an external resistor. However, timing accuracy may be improved by adding an external discharging resistor and/or charging resistor. The output connection may be configured as a tri-state output and may be driven high to charge and low to discharge the timing capacitor. A voltage reference may be used in determining a voltage trip point for timing and low voltage detection purposes. Temperature may be determined from either a trip voltage compared to a known voltage determined at a known temperature, or a current value of the current source compared to a known current value determined at a known temperature, times a constant.
