Abstract:
Described are various configurations for an amplifying optical demultiplexer. Various embodiments can receive an input signal comprising multiple sub-signals, and separate and amplify the signals within the demultiplexer. Some embodiments include a multistage demultiplexer with amplifiers located between a first and second stage. Some embodiments include a multistage demultiplexer with amplifiers located between a second and third stage.

Claim (Index 1):
A method of processing optical signal, the method comprising:\n receiving, by a multistage semiconductor demultiplexer having integrated semiconductor filters and integrated semiconductor amplifiers, an input signal having multiple optical signals, the integrated semiconductor filters comprising a Mach-Zehnder Interferometer (MZI) filter in an initial stage of the multistage semiconductor demultiplexer and additional MZI filters in an additional stage of the multistage semiconductor demultiplexer, and the integrated semiconductor amplifiers comprising semiconductor optical amplifiers between the initial stage and the additional stage; separating the multiple optical signals using the MZI filter in the initial stage; generating, within the demultiplexer and using the multiple semiconductor optical amplifiers, amplified optical signals by amplifying the multiple optical signals that have been separated by the MZI filter in the initial stage; and generating filtered optical signals by filtering the amplified optical signals using the additional MZI filters in the additional stage.
