Abstract :
Novel three-terminal field-induced charge-separation lasers (FICSLs) in VCSEL form were designed and fabricated. The new gain modulation mechanism of hole-electron separation was demonstrated for the first time by applying a variable gate voltage with a constant injection current to the active region.
