Abstract:
We report the optoelectronic characteristics dependency of a transistor vertical-cavity surface-emitting laser (T-VCSEL) on quantum wells (QWs) location at room temperature. TVCSEL used in this work has double QWs and graded-index (GRIN) separate confinement heterostructure (SCH). Using a numerical simulation based on physical models, demonstrated that the optical output power enhanced significantly (%43), threshold current decreased %32, and modal gain decreased %10 due to moving the QWs toward the emitter-base junction. While by moving the QWs toward the collector optical output power decreased %44, threshold current increased %80, and modal gain increased %25.
