We present a multifunctional photonic switch that monolithically integrates an InGaAsP/InP quantum well electroabsorption modulator and an InGaAs photodiode as a part of an on-chip, InP optoelectronic circuit. The optical multifunctionality of the switch offers many configurations to allow for different optical network functions on a single chip. Here we experimentally demonstrate GHz-range opt...

We report a novel coupling geometry for integrated waveguide photodetectors-a hybrid vertical coupling/butt coupling scheme that allows the integration of fast, efficient, photodetectors with conventional double heterostructure waveguides. It can be employed to yield a planar, or pseudo-planar, surface that supports further levels of integration. The approach is demonstrated with a 25pm-long p-...

A highly-integrated optical phase-locked loop with a phase/frequency detector and a single-sideband mixer (SSBM) has been proposed and demonstrated for the first time. A photonic integrated circuit (PIC) has been designed, fabricated and tested, together with an electronic IC (EIC). The PIC integrates a widely-tunable sampled-grating distributed-Bragg-reflector laser, an optical 90 degree hybri...

The first vertical-cavity surface-emitting laser diodes operating continuous-wave at room temperature at 1.54 mm emission wavelength are analyzed using a comprehensive numerical simulation procedure. These lasers employ strain-compensated InGaAsP multi-quantum wells sandwiched between GaAs/AlGaAs mirrors that are double-fused on the InP spacer layers at both sides. The model includes finite ele...

In this paper, the characteristics of longwavelength vertical-cavity surface-emitting laser (VCSEL) lasing at 1550 nm have been studied based on the influence of the oxide aperture radius. Using the oxide confined VCSEL model, we examine the static operations taking into account the carrier-noise, photon-noise and phase-noise including feedback of the external cavity. From the simulation, sever...
