Abstract: MEMS-actuated optical switches can be implemented on photonic chips. These switches are compact, essentially planar, simple to implement and include only one moving MEMS component per switch. The switches exhibit low optical loss, require low power to operate, and are simple to control and easy to integrate with other optical devices. Each switch has two optical waveguides that are optically coupled in an ON switch state and not coupled in an OFF switch state. An end or a medial section of one of the two waveguides may translate between the ON and OFF states to affect the coupling. Alternatively, a coupling frustrator may translate between the ON and OFF states to affect the coupling.

Abstract: An optical system includes a laser source that provides a beam of light, a photonic integrated circuit (PIC) with an input aperture, and an alignment fixture that has at least one actuator. The alignment fixture may be mounted on the PIC. The optical system is aligned such that the beam of light travels from the laser source to the alignment fixture and from the alignment fixture to the input aperture of the PIC. The alignment fixture can move in at least one direction upon actuation of the at least one actuator to adjust coupling between the laser source and the PIC. The at least one actuator may be a micro-electro-mechanical system (MEMS) structure actuated by an electrical signal.
