“…Many researches related to OPA have been reported [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20], and it is widely considered to be a key sensing modality for reliable autonomous systems, most notably for self-driving cars [21]. OPA is also promising in the field of free space optical communications, and there have been some related reports in recent years [22][23][24][25][26][27]. Among various forms of OPA, silicon-based OPA is compatible with CMOS processes, and has the advantages of low cost and easy to hybrid integration of optical and electronic components.…”

“…Recently, OPA transmitters (TX) capable of electrical adaptive beamforming, forming a beam of light and steering it electronically, have attracted a great deal of interest [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. An OPA transmitter consists of an array of radiating elements and can be used to engineer a desired optical wavefront.…”

“…An OPA transmitter consists of an array of radiating elements and can be used to engineer a desired optical wavefront. Such an optical transmitter has applications in systems such as LiDAR [28][29][30][31][32], point-to-point communication [26,27,33], lens-less projection [19], and holographic displays [34]. Large-scale OPA transmitters with more than a thousand radiating elements have been demonstrated with narrow beamwidth and high resolution [14][15][16][17][18].…”

Optical phased arrays (OPAs) on integrated photonic platforms provide a lowcost chip-scale solution for many applications. Despite the numerous demonstrations of OPA transmitters, the realization of a functional OPA receiver presents a challenge due to the low received signal level in the presence of noise and interference that necessitates high sensitivity of the receiver. In this paper, an integrated receiver system is presented that is capable of on-chip adaptive manipulation and processing of the captured waveform. The receiver includes an optoelectronic mixer that down-converts optical signals to radio frequencies while maintaining their phase and amplitude information. The optoelectronic mixer also provides conversion gain that enhances the system sensitivity and its robustness to noise and interference. Using this system, the first OPA receiver with a two-dimensional aperture of 8-by-8 receiving elements is demonstrated which can selectively receive light from 64 different angles. The OPA receiver can form reception beams with a beamwidth of 0.75 • over an 8 • grating-lobe-free field of view.

“…In fact, free-space optical communication is particularly interesting for long-range line-of-sight connections thanks to the high bandwidth and to the immunity to electromagnetic interference. In this context, the implementation of integrated optical phased arrays (OPA) has provided simple and precise free-space optical beam steering through the engineering of significant parameters such as emitter spacing, phase shift between adjacent elements, and emitter aperture, which lead to higher directivity and path reconfigurability [11][12][13].…”

Optical technology applied to on-chip wireless communication is particularly promising to overcome the performance limitations of the state-of-the-art networks on-chip. A key enabling component for such applications is the plasmonic antenna coupled to conventional silicon waveguides, which can guarantee full compatibility with standard optical circuitry. In this paper, we propose an antenna array configuration based on tilted plasmonic Vivaldi antennas coupled to a silicon waveguide. The details of the single antenna and of the array design are reported. The radiation characteristics of the array are suitable for on-chip point-to-point communication, i.e. in-plane maximum gain of 14.70 dB for an array with five antennas. The array exploits a travelling wave feeding scheme and, therefore, is compact in size (about 3.5 µm x 8.7 µm).
