Acousto-optic modulator for optical waveguides

An acousto-optic modulator arrangement includes an optical waveguide, such as an optical fiber, coupled to a substrate having an acoustic transducer formed thereon, by an acoustically-compatible solder composition. An acoustically-compatible solder composition provides advantageously low power refle...

Beschreibung
Zusammenfassung:	An acousto-optic modulator arrangement includes an optical waveguide, such as an optical fiber, coupled to a substrate having an acoustic transducer formed thereon, by an acoustically-compatible solder composition. An acoustically-compatible solder composition provides advantageously low power reflections at the substrate-solder and solder-optical waveguide interfaces for acoustic waves generated by the transducer. Such propagated acoustic waves are then useable to modulate a light signal propagating through the waveguide by an acousto-optic effect with an advantageous modulation efficiency.
