Patent ID: 7684659

Claim:
A method of constructing a fiber-optic gyroscope, the method comprising: optically coupling first and second optical fibers to an optical path of an interferometer having an outer surface; coupling at least a portion of the first and second fibers to the outer surface; and optically coupling the first and second fibers to an optical path of an integrated optics chip (IOC); wherein coupling at least a portion of the first and second fibers to the outer surface comprises: orienting a first portion of the first fiber in a first direction relative to the outer surface; orienting a first portion of the second fiber in a second direction relative to the outer surface and different from the first direction; orienting a second portion of the first fiber and a second portion of the second fiber such that the second portions of the first and second fibers converge toward one another; wrapping multiple turns of respective third portions of the first and second fibers around the outer surface in the same direction; looping a fourth portion of the first fiber and a fourth portion of the second fiber to be oriented in a direction opposite to the direction of the respective third portions; and orienting a respective fifth portion of the first and second fibers in a substantially sinusoidal configuration along the outer surface.
