Abstract:
A spectrometer includes an interferometer having a first interference arm and a second interference arm to produce interference patterns from incident light. At least one of the interference arms includes a series of cascaded optical switches connected by two (or more) waveguides of different lengths. Each optical switch directs the incident light into one waveguide or another, thereby changing the optical path length difference between the first interference arm and the second interference arm. This approach can be extended to multi-mode incident light by placing parallel interferometers together, each of which performs spectroscopy of one single mode in the multi-mode incident light. To maintain the compactness of the spectrometer, adjacent interferometers can share one interference arm.

Claim (Index 1):
A spectrometer, comprising:\n a beam splitter to split incident light into a first portion and a second portion; a first interference arm, in optical communication with the beam splitter, to receive the first portion of the incident light, the first interference arm comprising:\n a first optical switch switchable between a first state and a second state; \n a first waveguide having a first optical path length L 1  to receive the first portion of the incident light when the first optical switch is in the first state; and \n a second waveguide having a second optical path length L 2 , different than the first optical path length L 1 , to receive the first portion of the incident light when the first optical switch is in the second state; \n a second interference arm, in optical communication with the beam splitter, to receive the second portion of the incident light; and a single-element detector, in optical communication with the first interference arm and the second interference arm, to detect interference of the first portion of the incident light from the first interference arm and the second portion of the incident light from the second interference arm.
