Photorefractive semiconductor single-mode waveguides grown by gas-source molecular-beam epitaxy

Two semiconductor single-mode waveguides have been fabricated to study the photorefractive effect in epilayers grown on an InP:Fe substrate. The first experimental results obtained in these structures are reported. At 1.55-microm wavelength, a 0.53-cm(-1) gain is observed in contradirectional two-wa...

Description
Summary:Two semiconductor single-mode waveguides have been fabricated to study the photorefractive effect in epilayers grown on an InP:Fe substrate. The first experimental results obtained in these structures are reported. At 1.55-microm wavelength, a 0.53-cm(-1) gain is observed in contradirectional two-wave mixing and a 4-cm(-1) gain is measured in codirectional two-wave mixing with a 5.7-kV/cm applied field. The gain dependence versus the light intensity and the applied field is also discussed.
