Paper Abstract

Multi-Quantum Well (MQW) modulators have been demonstrated with a high contrast ratio of of 5:1 in an InGaAs/InAlAs p-i-n structure at 1.55 μm. Additionally, it was found that modulators that exploit the optical properties of resonant cavities can achieve contrast ratios at least three times larger than those that don't. The devices fabricated were measured to have modulation rates of greater than 30 MHz. Lastly, quantum efficiencies and responsivity measurements show that modulator would be able to detect incident light and coupled with electronics would "know" when to modulate.
