Abstract: An optic intensity modulator includes a substrate of an optic material that is conductive to light and acoustic waves and has both electrooptic and piezoelectric properties. A pair of associated elongated light waveguides is formed in the substrate, with the waveguides extending substantially coextensively with one another, and being separated from one another by a transverse distance that gradually varies along the courses of the waveguides. Each of two portions of light of substantially identical properties is launched into one of the waveguides for propagation longitudinally thereof, and different phase shifts are induced in the light portions as they propagate in the waveguides by imposing different variable electric fields onto each of the waveguides. The light portions are combined with one another subsequently to their emergence from the waveguides with attendant amplitude modulation of the combined output light due to interference between such phase-shifted light portions.

Abstract: A dual-ring-modulated laser includes a gain medium having a reflective end coupled to an associated gain-medium reflector and an output end, which is coupled to a reflector circuit through an input waveguide to form a lasing cavity. The reflector circuit comprises: a first ring modulator; a second ring modulator; and a shared waveguide that optically couples the first and second ring modulators together. The first and second ring modulators have resonance peaks that are tuned to be offset in alignment from each other to provide an effective reflectance having a flat-top response, which is aligned with an associated lasing cavity mode. The first and second ring modulators are driven in tandem based on the same electrical input signal, whereby the resonance peaks of the first and second ring modulators shift wavelengths in the same direction during modulation, and an effective reflectance stays within the flat-top wavelength range.
