ABSTRACT
Optical tristability is demonstrated with a positive feedback circuit composed of a twin-stripe laser diode, a p-i-n photodiode, and a transistor. A novel nonlinearity in the current/light characteristics of the twin-stripe laser diode is the key point in realizing the tristability. By changing the circuit parameters, optical bistability and differential gain characteristics can also be performed.

    By measuring the output signal of a SiC photodiode under short-pulse illumination with photon energies below the band gap, it was found that the response is determined by a second-order process, i.e., two-photon induced photoconductivity. This nonlinearity is suitable for realizing...

    The article states that laser diodes can destroy themselves in a few nanoseconds, so testing the response and stability of a feedback-stabilized laser-diode driver can be expensive. The simulator circuit presented in the figure shows a typical laser diode package, which contains not only the...

    This is a course to introduce the students to a basic optical link. An optical link has three main components, each with a specific function. The transmitter contains a light source, e.g., a light-emitting diode (LED), an edge-emitting laser diode (LD), or a vertical cavity surface-emitting...

    A two-terminal silicide Schottky-barrier collector phototransistor (SBCPT) integrated on a silicon-on-insulator waveguide was proposed and demonstrated using low-cost standard silicon processing technology. Owing to the current gain through the transistor action, the SBCPT at 5 V bias achieves a...

    The potential use of ZnO-based photonic and electronic devices has been demonstrated by the fabrication of prototype ultraviolet (UV) photodetector and field-effect transistor (FET) devices that contain films of p-type ZnO with arsenic as the p-type dopant. These p-type films have high...

    Traditionally, mirror design at the wavelengths important for fiber optic systems (1.3 and 1.55 μm) has suffered from the low refractive index step available between InP and its lattice-matched alloys; the InP/In0.53Ga0.47As combination provides the largest index step, but at λ=1.55 μm...
