    Abstract: A light source that includes first and second waveguides and a passive resonator for coupling light between the waveguides. The waveguides include a gain region for amplifying light of a desired wavelength, a transparent region, and an absorption region. The passive resonator couples light of the desired wavelength between the first and second transparent regions of the first and second waveguides and has a resonance at that wavelength. The resonator is preferably a microdisk resonator. The index of refraction of the microdisk resonator can be altered to select the desired wavelength. A second microdisk resonator having a different radius may be incorporated to increase the tuning range of the light source. The resonator is preferably constructed over the waveguides with an air gap between the resonator and the substrate in which the waveguides are constructed.

    Abstract: A band discontinuity reduction layer having a band gap energy larger than that of that of an MQW (multiple quantum well) absorption layer and smaller than that of a p-InP clad layer is provided between the MQW absorption layer and the p-InP clad layer. In addition, a band discontinuity reduction layer having a band gap energy larger than that of the MQW absorption layer and smaller than that of an n-InP clad layer is provided between the MQW absorption layer and the n-InP clad layer. Consequently, as a pile-up of carriers is suppressed, a semiconductor light modulator with an enhanced response speed can be obtained.

    Abstract: A light modulator having a reduced parasitic static capacitance includes a semiconductor substrate having a mesa section and a bonding pad section. A primary insulating film on the substrate continuously covers the mesa section and the bonding pad section. After a mask has been formed on a portion of the primary insulating film opposite the bonding pad section, the remaining portion of the primary insulating film is etched, followed by removal of the mask. After the removal of the mask, a second insulating film is formed continuously covering the primary insulating film opposite the bonding pad section and the mesa section so that a relatively thick insulating layer is present only opposite the bonding pad section.

    Abstract: A grating optical switch has at least one switch region for ON-OFF switch control of a signal light transmission and a signal light reflection, at least one input/output optical waveguide region for guiding the signal light to the switch, at least one coupler region for coupling the control light colinearly to the signal light and for guiding the control light to the switch region together with the signal light, and at least one separator region for separating the signal light and the control light. The switch region transmits the signal light when the control light is coupled while reflecting the signal light when the control light is not coupled.

    Abstract: An optical switch having a plurality of channel waveguides. At least one of which is a gain-guided channel waveguide. In operation, a light beam incident on one end face of the optical switch through one of the channel waveguides exits from the switch through one or another of the channel waveguides in accordance with current injected into the gain-guided channel waveguide. As a result, a compact low-voltage optical switch is possible. The channel waveguides may run parallel to each other, or may come together in a center portion in a X-shape, separated by a relatively small distance, or as a third alternative may be formed in a Y-shape, with a small distance separating the branches of said Y-shape.
