We demonstrate imaging of deep layers of mouse brain using three-photon fluorescence adaptive-optics based on 1300-nm femtosecond pulses and MEMS spatial-light-modulator. We show significant signal and resolution improvement for neurons imaged both in the cortex and in the hippocampus.

We have developed an unsupervised method to analyze fluorescence lifetime imaging microscopy data based on non-negative matrix factorization. Additionally, by modelling the Förster resonant energy transfer process between donor and acceptor fluorophores, we retrieve the dynamics and the distribution of donor-acceptor pairs.

A simple scheme for Millimeter wave generation employing optical heterodyning with Fabry Perot laser based optical frequency comb is proposed. We experimentally demonstrate the generation and distribution of 1.2 Gbps 64 QAM-OFDM on 65 GHz carrier over 25 km fiber, achieving BER within HD-FEC limits.

Iterative field reconstruction for dispersion compensation in IM/DD transmission systems is studied. Numerical simulation and a preliminary experiment show that the mixed use of Fienup input-output and Gerchberg-Saxton (GS) algorithms can give faster field reconstruction than the use of GS algorithm alone.

We demonstrate a 7.76-Mb/s optical camera communication system using a CMOS-driven micro-LED projector and a high-speed camera. PAM4 signals applied to 100 individual pixels were transmitted in an imaging multiple-input-multiple-output system. The results predict a potential data rate of gt 1 Gb/s using the full chip.

An integrated Lidar is designed with CWDM laser array. Its angle of view is doubled by using counter-propagating beams, angular resolution is doubled by leveraging orthogonal polarizations. Its overall performance is quadrupled. Within 60-nm wavelength-tuning range, it features 29° view together with 1.9° angular resolution.

We show that the minimum feature size of subwavelength grating slot waveguides can be increased from 60 nm to 120 nm with enhanced fabrication tolerance and only 13 nm/RIU reduction in the bulk sensitivity from 538 nm/RIU to 525 nm/RIU.

Optimal hyperparameters and inference accuracy for analog-based deep learning hardware is highly dependent on system architecture and component noise. We present AnalogVNN as a fully modular framework to easily model and train arbitrary analog photonic neural networks using the simple modular layer structures of PyTorch.

We propose a coherent multi-dimensional (wavelength, spatial mode, polarization, etc.) photonic tensor accelerator capable of matrix-vector, matrix-matrix, and batch matrix multiplications in a single clock cycle. A proof-of-concept $2times2$ matrix-matrix multiplication at 25GBd with 4.67 bit precision was experimentally demonstrated.

We demonstrate a time-delay reservoir computing network based on laser dynamics, where the delay time is asynchronous with the clock period of the input signal. The performance of this asynchronous network is proved to be more competitive than those of common synchronous networks.
