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.
