Abstract: An optical switch includes an array of optical fibers to conduct optical signals. A biconvex lens has a front convex surface facing the fibers' tips and has a back convex surface facing a microelectromechanical (MEMS) mirror. The MEMS mirror can be selectively oriented to reflect the optical signals incident to the MEMS mirror so the optical signal input from one fiber can be selectively routed to another of the fibers.

Abstract: An optoelectronic device is used with an optical fiber for data transmission and has a transmitter mounted on a printed circuit board (PCB) to emit light. A collimation lens on a lens block receives the light incident thereto. A microstructure on a reflective surface of the lens block has sections that reflect the light into attenuated portions. A focusing lens on the lens block focuses a first attenuated portion from first sections of the reflective surface to the optical fiber. Meanwhile, second sections of the reflective surface reflect a second attenuated portion to another reflective surface on the lens block. The second attenuated portion passes out of a refractive surface on the lens block to an receiver, which is mounted on the PCB adjacent the transmitter. The second attenuated portion of the light can be used to monitor the optical output of the transmitter.

Abstract: Described herein is a wavelength reference device comprising a housing defining an internal environment having a known temperature. A broadband optical source is disposed within the housing and configured to emit an optical signal along an optical path. The optical signal has optical power within a wavelength band of interest. An optical etalon is also disposed within the housing and positioned in the optical path to filter the optical signal to define a filtered optical signal that includes one or more reference spectral features having a known wavelength at the known temperature. The device also includes an optical output for outputting the filtered optical signal.
