Wavelength Selective Switching In Optical Communications

Micro-lens arrays are monolithic components manufactured from synthetic fused silica and a laser writing process, which are created for high accuracy array collimation and coupling. PowerPhotonic designs and develops these micro-lens arrays for applications involving coupling between laser sources, fiber and waveguide arrays, optical multiplexing, and optical switching. This application note discusses micro-lens arrays, as well as the technologies they are used in such as wavelength selective switching, WSS technology, and MEMS and LCoS switches.
