Two-dimensional optical beam steering using an InP photonic integrated circuit has been demonstrated. Lateral beam steering controlled by a 1-D phased array has been made easier through on-chip interferometer monitors. Longitudinal beam steering controlled by the input wavelength has demonstrated an efficiency of 0.14 • /nm. Very fast beam steering (>10 7 • /s) in both dimensions has been demonstrated as well. As the latest development, a widely tunable sampled-grating distributed Bragg reflector laser has been monolithically integrated and 2-D beam steering has been demonstrated with this on-chip tunable laser source.Index Terms-Light detection and ranging (LIDAR), optical beam steering, optical phased array (OPA), photonic integrated circuits (PICs).

“…• was also demonstrated in a two-dimensional petal-shaped holey VCSEL thanks to a suited refractive index profile in the holey region and near the optical Advances in Optical Technologies 9 aperture [61]. In addition, the use of nonperiodic high-contrast subwavelength mirrors (SWG) proposed recently to replace thick Bragg mirrors in tunable MEMS-VCSEL [62] is considered as a future solution for active phase front correction and dynamic focusing [63,64].…”

We describe the main recent technological approaches that associate micro-optical elements to VCSELs in order to control their output beam and to improve their photonic integration. These approaches imply either a hybrid assembly or a direct integration technique. They are compared with regards to their tolerance to alignment errors and to their ease of implementation onto arrays of devices at a wafer level. In particular, we detail the integration techniques we have developed for self-aligned polymer microlens fabrication for beam collimation and short distance beam focusing. Finally, designs to achieve active micro-optics or to exploit novel nanophotonic effects are discussed.

“…However, those devices are bulky and the speed of steering is also slow. There have been various approaches using laser diodes for beam steering including in-plane laser arrays, photonic crystal lasers, phase-locked VCSEL arrays and so on [3,4,5]. While non-mechanical beam steering was demonstrated, the number of resolution points N (= θ rmax /θ div ), which can be defined as the maximum beam-steering angle θ rmax divided by a beam divergence angle θ div , has been limited below 100.…”

Abstract:We demonstrate the monolithic integration of an electrothermal beam deflector based on a slow-light Bragg reflector waveguide with a VCSEL for the first time. The slow-light mode is laterally exited from a VCSEL and is directly coupled to the slowlight waveguide. The chip size is smaller than 300 μm. The fabrication process is the same as that of conventional VCSELs. Continuous electro-thermal beam steering of over 9ﾟ with a diffraction-limited divergence angle of 2.2ﾟ is obtained. In addition, a potential in compact and high-resolution on-chip beam deflectors is suggested.
