Passive Aperiodic Optical Phased Array based on Uniform Random Shuffle
Bowen Yu, Dachuan Wu, Yasha Yi
Grating lobes arise from the periodic nature of element spacing in the optical phased array. Essentially, the phased array performs the Spatial Fourier Transform on light; the stee…
Photonic integrated circuit with multiple waveguide layers for broadband high-efficient on-chip 3-D optical phased arrays in light detection and ranging applications
Dachuan Wu, Bowen Yu, Venus Kakdarvishi +1
Traditional photonic integrated circuit (PIC) inherits the mature CMOS fabrication process from the electronic integrated circuit (IC) industry. However, this process also limits t…
High efficiency end-fire 3-D optical phased array based on multi-layers Si3N4/SiO2 platform
Dachuan Wu, Yasha Yi, Yuxiao Zhang
Beam steering device such as optical phased array (OPA) is a key component in applications of solid-state Lidar and wireless communication. The traditional single-layer optical pha…
Metalens With Artificial Focus Pattern
Mao Ye, Vishva Ray, Dachuan Wu +1
Metalens as one of the most popular applications of emmerging optical metasurfaces has raised widspread interest recently. With nano structures fully controlling phase, polarizatio…
