Reduction of Cavity Length in λ-Scale Embedded Active-region Photonic Crystal (LEAP) Lasers

摘要

We have developed photonic crystal (PhC) lasers, in which extremely short active regions (420 nm~1260 nm) are embedded with an InP PhC slab. 4-μΛ threshold currents and 1-fJ/bit operating energies were achieved with 840-nm-long and 1260-nm-long active regions consisting of 3 and 2 QWs, respectively.
