We theoretically present in-plane multiple guided emissions of metallically confined microdisk lasers which can be applied to drive multiple elements in compact photonic integration at the same time. Two to four-port microdisks with transverse magnetic and electric polarizations are investigated based on finite difference time domain simulation and...
A novel surface-emitting superluminescent diode (SLD) having a round active region surrounded by a circular grating is theoretically investigated. When the superluminescent light produced in the active region transmits to the passive region, it is coupled out of the device by the detuned circular grating, forming a symmetric surface-emitting beam t...
In this Letter, we propose a hybrid plasmonic nanosystem consisting of a silver cladding layer with a semicylinder bump on top of InGaAsP nanowire. Because of the coupling between the dielectric waveguide mode and surface plasmon polariton mode, the hybrid plasmonic mode can exhibit low loss with strong field localization. The finite element method...
InAlGaAs/InP cylinder microlasers with radius of 15 mu m, connected with two 2 mu m-wide output waveguides, are fabricated by conventional photolithography and inductively coupled-plasma etching techniques. Room-temperature continuous-wave electrically injected singlemode operation is realised at the lasing wavelength of 1577 nm and sidemode suppre...
It is desirable to simplify process, lower cost and improve characteristics of the integrated optoelectronic functional devices. A novel technique named as selective area growth double stacked active layer(SAG-DSAL) was introduced. A monolithically integrated and electro-absorption modulated distributed feedback laser was developed with this techni...
Molecular beam epitaxy growth of GaAs-based long-wavelength metamorphic InAs/InGaAs quantum dots (QDs) is investigated. With optimized multi-step-graded InGaAs metamorphic buffer layers and growth conditions, room temperature 1.46 mu m emission from InAs/In(0.15)Ga(0.85)As QDs is realized, and broad-area laser diodes are fabricated with a very low ...
Optical amplification is demonstrated in a slab photonic crystal waveguide (PCW). Nonlinear dispersive gain FDTD and traveling-wave rate equation method (TWRE) are used to design a photonic crystal semiconductor optical amplifier (PC-SOA). Optical amplification based on slow light of PCW can be obtained not only in theory but also in experiment. In...
