“…SWG reflectors integrated in Fabry-Perot resonators have also been used to realize vertical-cavity surface-emitting lasers (VCSELs) 19 by replacing the conventional DBRs, and also to show novel MEMS devices. 9,20 This asymmetric Fabry-Perot resonator is equivalent to a conventional Gires-Tournois interferometer, with a bottom mirror exhibiting nearly unity reflectivity and a less reflective top mirror, that is widely used for pulse compression bacause of its highly dispersive phase response.…”

Spatiotemporal control of optical wavefronts is of great importance in numerous free-space optical applications including imaging in 3D and through scattering media, remote sensing, and generation of various beam profiles for microscopy. Progress in these applications is currently limited due to lack of compact and high-speed spatial light modulators. Here we report an active antenna comprising a free-space coupled asymmetric Fabry–Perot resonator that produces a phase-dominant thermo-optic modulation of reflected light at frequencies approaching tens of kilohertz. As a proof of concept for spatial light modulation, we demonstrate a 6 × 6 array of such active antennas with beam deflection capability. The robust design of our silicon-based active antenna will enable large-scale integration of high-speed, phase-dominant spatial light modulators.

With this approach it is possible to substitute DBR for a heat spreader embodying this kind of structure as a mirror Huang et al (2007), Chang-Hasnain andYang (2012).…”

High refractive index contrast gratings (HCGs) with their extraordinary optical properties are very interesting candidates to substitute Distributed Bragg Reflectors as mirrors in optoelectronic semiconductor devices. In this work we present results of optical examination of a large scale HCG structure fabricated by focused-ion beam etching technique. The measured reflectance spectra exhibit a strong dependence on polarization of incident light, which confirms theoretical predictions. We also studied optical properties of a cavity formed by the HCG stacked on a wafer containing a VECSEL-like epitaxial structure.

“…Thereafter, the extraordinary and intriguing properties of HCGs have been exploited to design and build various optical elements such as high-Q Fabry-Perot resonators [4], top mirrors in vertical-cavity surface-emitting lasers [5,6], one-and two-dimensional hollow-core low-loss optical waveguides [7], slow-light waveguides [8], planar focusing reflectors and lenses [9,10] In a recent study, we have shown that a two-dimensional HCG structure with optimized geometrical parameters can be utilized for implementing a broadband circular polarizer [18]. The optimized geometrical parameters have been suggested by benefiting from the periodic dielectric slab waveguide interpretation, which is studied rigorously in [19].…”

Fabrication and experimental characterization of a broadband quarter-wave plate, which is based on two-dimensional and binary silicon high-contrast gratings, are reported. The quarter-wave plate feature is achieved by the utilization of a regime, in which the proposed grating structure exhibits nearly total and approximately equal transmission of transverse electric and transverse magnetic waves with a phase difference of approximately π/2. The numerical and experimental results suggest a percent bandwidth of 42% and 33%, respectively, if the operation regime is defined as the range for which the conversion efficiency is higher than 0.9. A compact circular polarizer can be implemented by combining the grating with a linear polarizer.
