To address this challenge, Yagyu and Kuba’s team are working with Kyoto University on developing new photonic-crystal surface-emitting lasers (PCSELs), a type of laser diode. These contain a ...

In addition to the optical considerations common with all semiconductors, diode laser structures must also incorporate a means of injecting an electrical current into the active region.

CryLaS GmbH designs, manufactures and sells pulsed and cw diode-pumped solid-state lasers in the UV, VIS and IR spectral range. The lasers are used for OEM and demanding scientific applications in ...

The large mismatch in crystal lattice parameters and thermal expansion coefficients between III-V and Si materials inevitably initiates the formation of crystal misfit defects, which are known to ...
