WebJul 1, 2024 · Optical phased arrays (OPAs) are devices that use the coherence of light to control the interference pattern in the far field, which enables them to steer a laser beam with no moving parts. As such, OPAs have potential applications in laser communications, target acquisition and tracking, metrology, and directed energy. WebDec 24, 2024 · The majority of the nonmechanical approaches to beam steering create a tilted optical path delay (OPD) to change the wavefront, but some directly create a phase delay. OPD-based approaches may be true time delay, with no resets or modulo 2πn optical phased arrays that have resets.
WebWe experimentally demonstrated a 1000-element silicon optical phased array based on a slab grating and half-wavelength-spacing waveguide array. A large beam steering range of >140° and a small beam divergence of 0.16° were achieved. © 2024 The Author (s) PDF Article Presentation Video More Like This WebNov 3, 2024 · A practical two-dimensional beam steering solid-state system based on the synthesis of one-dimensional wavelength tuning and a one-dimensional optical phased array is demonstrated and investigated.
