Abstract:
A photonic integrated circuit including a beam launching waveguide, a local oscillator waveguide, a target interferometer, and a reference interferometer all integrated on a chip. The beam launching waveguide transmits target electromagnetic radiation off the chip and receives a retroreflection of the target electromagnetic radiation from a target off the chip. The target interferometer interferes the retroreflection with a local oscillator field transmitted from the local oscillator waveguide so as to form a target interference signal. The reference interferometer interferes a portion of the target electromagnetic radiation that does not leave the chip with the local oscillator field transmitted from the local oscillator waveguide to form a reference interference signal. The difference between the reference interference signal and the target interference signal is used to measure a distance to the target from the chip.

Claim (Index 8):
The method of  claim 6 , further comprising:\n electromagnetically coupling an optical system to the circuit, wherein: the optical system collimates the target electromagnetic radiation transmitted off the circuit and transmits the target electromagnetic radiation to the target, and optical path lengths of the waveguides are selected so as to at least partially compensate for changes in optical path length through the optical system due to thermal variations.
