Fabrication and molecular beam epitaxy regrowth of first-order, high contrast AlGaAs/GaAs gratings
We present a fabrication technique and molecular beam epitaxy MBE regrowth of first-order, high contrast AlGaAs/GaAs diffraction gratings for laser emitting at 980 nm. An immersion holography technique is used to uniformly pattern first-order gratings with a pitch of 155 nm. MBE is used to overgrow Al0.75Ga0.25As on etched GaAs gratings. It is found that slow growth rates with optimum arsenic o...
متن کاملPhase Matching in presence of feedback: Higher order terms and enhancement of nonlinear interactions
Our study shows that higher terms in phase matching conditions, usually neglected, can in fact drastically affect the dynamics in distributed feedback gratings. We showed that phase matching conditions and standard Bloch theory are totally inadequate to predict optimum second harmonic generation when fields’ overlap and localization effects rule the nonlinear dynamics. We designed an optimized ...
متن کاملSpatial processing of complex stimuli in the amblyopic visual system.
Thresholds for detection and discrimination of the polarity (phase) of repetitive gratings with a ramp luminance profile were compared to sine-wave thresholds in normal and amblyopic observers. In the high-frequency range (4 cy/deg), normal observers detected ramp-wave gratings when the contrast of the fundamental spatial frequency was close to its independent threshold and discriminated the po...
متن کاملSurface-normal emission of a high-Q resonator using a subwavelength high-contrast grating.
We report a novel high-quality (Q) factor optical resonator using a subwavelength high-contrast grating (HCG) with in-plane resonance and surface-normal emission. We show that the in-plane resonance is manifested is by a sharp, asymmetric lineshape in the surface-normal reflectivity spectrum. The simulated Q factor of the resonator is shown to be as high as 500,000. A HCG-resonator was fabricat...
متن کاملEnhanced second-harmonic generation in AlGaAs/AlxOy tightly confining waveguides and resonant cavities.
We demonstrate second-harmonic generation (SHG) from sub-micrometer-sized AlGaAs/AlxOy artificially birefringent waveguides. The normalized conversion efficiency is the highest ever reported. We further enhanced the SHG using a waveguide-embedded cavity formed by dichroic mirrors. Resonant enhancements as high as approximately 10x were observed. Such devices could be potentially used as highly ...
