Si photonic-electronic monolithically integrated optical receiver with a built- in temperature-controlled wavelength filter

We present a Si photonic-electronic integrated ring-resonator based optical receiver that contains a temperature-controlled ring-resonator filter (RRF), a Ge photodetector, and receiver circuits in a single chip. The temperature controller automatically determines the RRF temperature at which the maximum transmission of the desired WDM signal is achieved and maintains this condition against any temperature or input wavelength fluctuation. This Si photonic-electronic integrated circuit is realized with 0.25-mu m photonic BiCMOS technology, and its operation is successfully confirmed with measurement.
