Abstract: Optical multiplexers, optical demultiplexers, optical modules including the same, and methods of making and using the same are disclosed. The optical multiplexers include first and second structural blocks and a beam combiner. The first and second structural blocks each include at least one mirror and at least one filter, and are configured to combine a plurality ofindividual optical signals into a multi-channel optical signal. The beam combiner includes one or more mirrors and one or more filters, and is configured to combine the multi-channel optical signals into a further multi-channel optical output signal having the same number of channels as the multi-channel optical signals. The optical demultiplexers are structurally similar to the optical multiplexers, but provide a complementary or reverse function. The present multiplexers and demultiplexers reduce skew and/or accumulation of the geometric error over the channels in the multi-channel optical signal output from the multiplexer or input into the demultiplexer.

Abstract: An optical or optoelectronic receiver, an optoelectronic transceiver including the same, and a method and system for protecting a photodetector in the same are disclosed. The method of protecting a photodetector generally includes providing a control voltage to the photodetector so that a current flows through the photodetector, and determining that a transient event has occurred or a transient state exists in the receiver. During the transient event or transient state, the method maintains the control voltage at a normal operating voltage when the current through the photodetector is at or below a predetermined threshold current, and switches the control voltage to a safe mode voltage when the current through the photodetector is above the predetermined threshold current.
