Abstract

A compact delay stage for phase delaying a light signal to provide increased amounts of phase delay to a light signal. A plurality of reflective structures are configured to provide a delay path to the light signal. One of the reflective structures is configured to accept the light signal and direct the light signal between the reflective structures a predetermined selectable number of times until the light signal has completed the delay path thereby translating the light signal into a delay signal. One of the reflective structures is configured to provide egress to the delayed signal to exit the compact delay stage.
