“…These results hold promise that the reported algorithm is an efficient way to accomplish simultaneous phase and amplitude modulation in the Fourier domain with off-the-shelf devices capable of performing complex convolution on 2 million optical channels in parallel. Such a system is of high interest in developing optical filters, and processors, for numerous applications including optical cryptography, 12 where neglecting phase modulation can lead to impractical bit-error rates.…”

“…Optical real-time dynamic data processing has several applications including accelerating tensor algebra, which usually creates a bottle-neck in in silico machine learning, 1-10 cryptography, [11][12][13][14][15][16][17] digital holography, [18][19][20][21][22][23][24] and more optical computing algorithms [25][26][27][28][29][30][31][32][33][34] is given their high computational overhead. Alongside that, cryptography algorithms are highly dependent on computationally hungry data compression algorithms to provide the necessary level of security and meet common network specifications, while image processing Machine Learning algorithms dependent heavily on the speed of convolution and area dot product multiplication as their major computation budget consumer.…”

Dynamic real-time optical processing has significant potential for accelerating specific tensor algebra. Here we present the first demonstration of simultaneous amplitude and phase modulation of an optical two-dimension signal in the Fourier plane of a thin lens. Two spatial light modulators (SLMs) arranged in a Michelson interferometer modulate the amplitude and the phase while being simultaneously in the focal plane of two Fourier lenses. The lenses frame an interferometer in a 4f-system enabling full modulation in the Fourier domain of a telescope. Main sources of phase noise and losses are discussed such as native to SLMs non-linear inter-pixel crosstalk, variability in modulation efficiency as a function of projected mask parameters, and Fresnel's optics limitations. Such a system is of extreme utility in rapidly progressing fields of optical computing, hardware acceleration, encryption, and machine learning, where neglecting phase modulation can lead to impractical bit-error rates.

“…Photonic processors are poised to have a huge impact on the future of technology due to their capacity to conduct computations at fast speeds while consuming less energy. The photonic processors are applicable to a vast array of applications, including high-performance computing, data centers, artificial intelligence, quantum computing, highspeed communication system [1]- [3], GPU accelerators [4], and photonic computing [5]- [8]. The most critical part of the research of silicon photonics is the exploration of high-speed 2D and 3D materials and corresponding applications such as light sources [9], electric-optical modulators [10]- [23], and photodetectors.…”

Advancements in nanophotonics have raised the bar for optoelectronic devices, demanding ultra-compact size, fast speeds, high efficiency, and low energy consumption. Emerging materials hold the potential to meet these demands, enabling the creation of high-performing optoelectronic devices. We present our latest breakthroughs and demonstrate device prototypes made from various materials, pushing the boundaries of optoelectronic performance.

“…Free-space optical communication (FSOC) uses optical wavelength (from ultraviolet to infrared) to achieve data transmission through the atmosphere without the requirement of a physical communication link. [1][2][3][4][5][6][7][8][9][10][11] By leveraging the advantage of wider spectrum range in optical bands and compact spatial confinement from a laser beam, FSOC has already provided the ability to cater for high-capacity optical data transmission demand such as using wavelength division multiplexing (WDM) in the Tb/s regime. 12 Meanwhile, confined beam divergence guarantees the security of the communication link to a higher level since a third-party detector could intercept the transmitting beam only when it is placed close to the FSOC path.…”
