Abstract :
The first results on low power positive-intrinsic-negative (PIN) diode modulator structures using strained molecular beam epitaxy (MBE) on GaAs are presented. A comparison of transmission, reflection and photocurrent spectra for these nonresonant devices, with those fabricated from InGaAs/GaAs indicates larger modulation with a maximum change in reflection of >42% being observed at 5 V bias at a wavelength of 0.06 μm
