Abstract
A monolithically integrated displacement sensor has been fabricated in the GaAs/AlGaAs material system The device is configured as a Michels on interferometer and consists of a DBR laser, a directional coupler, transparent waveguides and a photodetector. Interference fringes could be seen at measurement distance of up to 45cm, requiring only the ali gnment of an external GRIN lens for beam collimation.
