<p>Disclosed is a Sagnac Interferometer comprising a waveguide loop section and a modulation section wherein the modulation section is positioned outside the waveguide loop and both have a modulation function and a splitting function, the modulation function being based on electro-optical or thermo-optical modulation. This SI can be used as a versatile light modulator using thermo-optical and electro-optical effects, both in the transmission mode (performing the same functions as a Mach-Zehnder Interferometer) and in the reflection mode (performing the same functions as a Michelson Interferometer).</p> |
