We propose and demonstrate a measurement technique of the intrinsic modulation responses of semiconductor lasers with high sensitivity in a wide modulation frequency range. The technique is based on the two-tone optical modulation and lock-in detecti

A novel configuration of mutually injection-locked directly modulated lasers (DMLs) for generating in-phase quadrature (IQ) optical signals is proposed and numerically investigated by using rate equations. Two DMLs coupled with a high-Q ring resonato

We numerically investigate spin-controlled vertical-cavity surface-emitting lasers (spin-VCSELs) for local oscillators, which are based on an injection locking technique used in coherent optical communications. Under the spin polarization modulation

We propose and numerically investigate the use of birefringent vertical-cavity surface-emitting lasers (VCSELs) under the injection and modulation of spin polarized electrons for application to analog radio over fiber (RoF) systems. Injection current

Recently, we directly observed the out-of-plane Dresselhaus spin–orbit (SO) interaction field and extracted the SO coefficient β from InGaAs (110) quantum wells (QWs). However, the extracted β was much larger than that of the (001) QWs, which yie
