Wide-Angle Sidelobe-Free Steering of Blue Light with an Active Optical Phased Array
We demonstrate an optical phased array at λ = 488nm consisting of a thermo-optically tuned end-fire array coupled to a slab grating emitter. 54.4° of sidelobe-free beam steering, 9.8dB average sidelobe suppression, and 15 resolvable spots are achieved.
