“…In our scheme, if we reduce the size of the antenna, the number of SWG bars in a pixel will be lower, and additional loss will be induced due to the lack of lateral mode confinement. 30 This can be circum-7 vented by several approaches including the effective index method 31 and the phase gradient mirror approach, 32 to further shrink the size of the antennas. Alternatively, even without having a smaller pixel pitch, one can think of enlarging the deflection angle limit using appropriate magnification optics to access a larger spatial frequency.…”

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.

“…The estimated I th of 0.99 mA is similar as that of long-wavelength VCSELs with a similar mode size. Since the transverse mode is gain-guided in the current hVCL sample, the threshold will be able to be further reduced by introducing a guiding scheme, e.g., a heterostructure in the HCG [3]. Fig.…”

“…It can provide a reflectivity close to 100 % over a broad wavelength range [1], as well as control over reflection phase [2][3][4][5]. Based on these properties, many interesting verticalcavity laser (VCL) structures with novel functionalities have been realized [6][7][8][9][10][11][12][13][14][15][16][17][18].…”
