Abstract:
A monitoring and control assembly for an optical system includes a tunable laser. The laser generates a divergent output beam along an optical axis. A first photodetector is provided. A wavelength selective filter is tilted at an angle relative to the optical axis that provides an angular dependence of a wavelength reflection of the wavelength selective filter and directs the reflected output beam towards the first photodetector.

Abstract:
A wafer assembly that includes a wafer substrate. A plurality of micro-optomechanical or micro-optoelectrical devices are positioned on a surface of the wafer substrate. Each micro-optomechanical or micro-optoelectrical device has a seal surface. A plurality of seal caps are coupled to the micro-optomechanical or micro-optoelectrical devices. Each seal cap has a seal ring. The seal cap seal ring is coupled to a seal surface of the micro-optomechanical or micro-optoelectrical device to form a hermetic seal.
