WebThe main focus of this work is the fabrication and experimental demonstration of a buried heterostructure (BH) photonic crystal laser bonded to a silicon wafer, illustrating the effective single-platform active-passive material integration method. KW - Photonic crystals. KW - Indium phosphide. KW - III-V semiconductor materials. KW - Cavity ... WebInGaAsP/InP buried heterostructure (BH) lasers with semi-insulating InP current blocking layers have been extensively studied as ultra-high speed light sources because of their small parasitic capacitance. So far they have been demonstrated using vapor phase epitaxy (VPE) [1-5] and metalorganic chemical vapor deposition (MOCVD) epitaxy [6,7].
