چکیده
Room-temperature continuous-wave operation of large-area (120 microm x 980 microm) GaAs/AlGaAs graded-refractive-index separate-confinement heterostructure lasers on (100) Si substrates has been obtained. Minimum threshold-current densities of 214 A/cm(2) (1900-microm cavity length), maximum slope efficiencies of about 0.8 W/A (600-microm cavity length), and optical power in excess of 270 mW/facet 900-microm cavity length) have been observed under pulsed conditions.

We report on the first electrically pumped continuous-wave (cw) InAs/GaAs quantum dot (QD) lasers monolithically grown on on-axis Si (001) substrates without any intermediate buffer layers. A 400 nm antiphase boundary (APB) free epitaxial GaAs film with a small root-mean-square (RMS) surface roughness of 0.86 nm was first deposited on a 300 mm standard industry-compatible on-axis Si (001) subst...

We report the first operation of an electrically pumped 1.3-μm InAs/GaAs quantum-dot laser epitaxially grown on a Si (100) substrate. The laser structure was grown directly on the Si substrate by molecular beam epitaxy. Lasing at 1.302 μm has been demonstrated with threshold current density of 725 A/cm2 and output power of ~26 mW for broad-area lasers with as-cleaved facets at room temperature....

Introduction: The proposal by Kondow and co-workers [1] of GaInNAs active regions for temperature insensitive GaAs-based lasers has led to significant success in the 1.3 mm regime, and performance currently exceeds that of competing InP-based devices. This effort has yielded InGaAs=GaAs lasers that emit out to 1.25 mm with exceedingly lowthreshold current densities [2], and emission has been ex...

III Two types of III-V diode lasers have been developed for new emission wavelengths. We have obtained emission at 0.9 to 1.06 Jim nom quantum-well lasers with a strained InGaAs active layer and AlGaAs confining layers. Organometallic vapor phase epitaxy (OMVPE) was used to grow the layers on GaAs substrates. These InGaAs/AlGaAs lasers have achieved threshold current densities as low as 65 Afcm...
