Stripe width dependence of internal quantum efficiency and carrier injection delay in lateral current injection GaInAsP/InP lasers

摘要

Internal quantum efficiency and carrier injection delay time in lateral-current-injection (LCI) lasers fabricated on a semi-insulating (SI)-InP substrate were evaluated for various stripe widths. As the results, it was confirmed that narrower stripe width (< 2 µm) can give better static and dynamic performances.
