High-performance surface-normal modulators based on stepped quantum wells

Surface-normal modulators based on stepped quantum wells at /spl lambda//spl sim/1.55 /spl mu/m are demonstrated. These devices have nearly two times better efficiency and 7 dB higher extinction ratio compared to devices with rectangular and coupled-quantum wells.
