Abstract: The method and apparatus for compensating a photo-detector allows both regulation and monitoring of the photo-detector to be performed with a common digital controller. The controller accepts input of monitored operational parameters including received signal strength and temperature. The controller provides as an output a bias control signal which regulates a positive the positive or negative side bias voltage power supply for the photo-detector. The controller maintains the bias voltage to the photo-detector at levels which optimize the gain and signal-to-noise ratios for the photo-detector thereby facilitating the decoding of the received signal over a broad range of signal strengths and temperatures. The controller includes a corresponding digital signal strength and temperature compensators the outputs of which summed with a summer to provide the bias control signal. The digital signal strength compensator also provides as an output a monitor signal a level of which corresponds to the actual signal strength received by the photo-detector after compensation for the variable gain of the photo-detector resulting from the bias voltage level. A transceiver as well as methods and means for monitoring a photo-detector are also disclosed.

Abstract: An integrated optical pickup device for a magnetooptical recording medium (e.g. a magnetooptical recording disk) and/or an optical recording medium (e.g. an optical recording disk) in which a plurality of focusing grating couplers are formed on an optical waveguide layer manufactured on a substrate. A light reflected from a magnetooptical disk or an optical disk is guided by the focusing grating couplers into the waveguide layer to be separated and to be converged therethtough. The converged lights are detected so as to produce a tracking error signal, a focusing error signal, and an information readout signal. The plural focusing grating couplers are fabricated at an identical location on the waveguide in a superimposed fashion. This increases the utilization efficiency of reflection light per each unitary area of the focusing grating couplers and hence the signals are obtained in a stable state. Between a semiconductor laser and a collimation lens, there is formed a composite beam splitter having two reflection surfaces. Reflection lights from the magnetooptical disk are respectively reflected by these reflection surfaces and are then received by photosensors. Analyzers are disposed respectively on front sides of the photosensors. The analyzers respectively have polarization directions orthogonal to each other. Each photosensor includes three-partition photodiode. The beam sizing method and the push-pull detection methods are used for detecting the focusing and tracking errors. The optical pickup device can also used to read data from an optical disk. A prism is disposed between a semiconductor laser and a collimation lens. The prism has two reflection surfaces. Reflection lights from a magnetooptical disk are respectively reflected by these reflection surfaces to be received by photosensors. On front sides of the photosensors, there are respectively arranged analyzers respectively having polarization directions orthogonal to each other. <IMAGE>

Abstract: Subtractive CDMA demodulation optimally decodes a coded information signal embedded in many other overlapping signals making up a received, composite signal. A radio receiver correlates a unique code corresponding to the desired signal to be decoded with the composite signal. Moreover, after each information signal is successfully decoded, it is recoded and removed from the composite signal. As a result, subsequent correlations are performed with greater accuracy. Subtractive CDMA demodulation is enhanced by decoding the composite signal in the order of strongest to weakest signal strength. Interference caused by the presence of the strongest information signal and the composite signal during the decoding of weaker signals is removed. The individual information signals are assigned a unique block error correction code which is correlated with the composite signal using Fast Walsh transforms. Correlated signals are recoded using inverted Fast Walsh transforms and removed from the composite signal.
