Membrane-Based Receiver/Transmitter for Reconfigurable Optical Wireless Beam-Steering Systems

InP membrane integrated photonics research

“…Therefore one can create a compact receiver device which monolithically integrates flexible and high-efficiency surface grating antennas and broadband photodiodes [156]. A step further can be the addition of directly modulated laser diodes and on-chip amplifiers, to form endterminal transceivers [157,158], or wavelength multiplexers to enable WDM [155]. InP membrane technology can offer all of these BBs in a single material system, thereby greatly reducing the complexity and cost of processing and assembly.…”

“…The grating couplers used in this first demonstration can be replaced by other integrated optical antenna concepts with wider FoV. Potential candidates include metasurfaces and on‐chip microlenses …”

Photonic integration technologies for indoor optical wireless communications

“…Reconfigurable transceivers can be a promising low-cost solution, which acts as receiver or transmitter using same set of devices. This concept has been proposed in [72], which is schematically shown in Figure 8. The key element in such concept is a reconfigurable gate, which can be realized by a p-i-n diode.…”

“…Such reconfigurability needs to be operated in divided time, which has potential in applications such as the broadcast and data exchange among wireless devices. Initial demonstrative experiment has been carried out [72]. In the work, a p-i-n diode was integrated with a grating coupler, forming a basic element of the reconfigurable receiver.…”
