Modern optoelectronic components have very tight coupling tolerances. Small misalignments of a strong lens that occur during the alignment and bonding process seriously degrade optical coupling. A weak lens is actively mounted using a flexure to correct misalignments of the strong lens. Since the weak lens does not exert as much steering force on a beam for a similar movement as the strong lens, misalignments that may occur during weak lens positioning and bonding do not appreciably degrade coupling.

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.
