Abstract
An integrated zig-zag transceiver module for multiplexing and demultiplexing several wavelengths achieves a high level of integration by combining several electronic and optical elements into TO headers with lids. A photodetector, a transimpedance amplifier (TIA), a lens, and a thin-film filter are integrated into a single TO can, with the filter and lens being designed for off-axis illumination and focusing. A VCSEL, a lens, and a thin-film filter are integrated into a single TO can, with the filter and lens being designed for off-axis beam steering and collimation.
