“…Its dimensions are Ф 55 mm x 25 mm, which is a volume of about 60 times more. Even Micro Electro Mechanical Systems (MEMS) which are known to be small devices, require typical 20 mm x 20 mm x 10 mm size [10], which is still 4 times more than PMP deflector. Thus, the optical deflector application particularly suits to the PMP actuation technology.…”

The recent progresses made in the manufacturing of new plasmonic photomobile films are offering innovative solutions for light induced motion actuators and devices. Indeed, such films can be assimilated as transducers thanks to their ability to convert light into displacement with strokes up to several millimeters. By adjusting the incident light parameters (wavelength, exposure time…) the photomobile films actuation can be controlled to answer many applications requesting high displacements and low forces. In these regards, the behaviour of the photomobile films were characterized prior to their integration in more complex devices. Then, several proof-of-concepts of these devices were manufactured to try to bring new functionalities to the market such as light driven optical switch, optical micro-valve, and deflector: The optical switch features interesting properties in term of electrical insulation by eliminating the dark currents responsible for noise in image sensors. It also exploits the large stroke of the photomobile films to achieve the standard electrical insulation distance versus emitter voltage. Light driven micro-valves/micro-pumps are suitable for delivering a small quantity of fluids with high precision for example in medical devices. Using this technology, a fluid circuit can be opened and closed when light is switched from on to off (or inversely) without embedded electric power. Optical deflectors are used widely in optical pointing applications where fast responses and/or high precisions are critical. An appropriate understanding of the photomobile films behaviour enables to control the direction of the beam deflection within large angular ranges.

“…Current state-of-the-art MEMS FSMs features simultaneous 2D steering range, impressive bandwidth, and lower cost but still requires additional optics and have its inherent drawbacks highlighted in section 1.1 above. A prominent issue with MEMS-FSM is the reflector thermal expansion, wavefront distortions and its inability to handle higher laser power beyond 23dBm [7].…”

We present concept design of an innovative, compact, non-mechanical optical beam steering antenna with an experimental liquid crystal beam shaper optimized for lean platforms. Laser communication terminals in air and space-borne platforms must fulfil the low-SWaP (size, weight, and power) design philosophy which is often a challenging task when utilizing mechanical steerers like prisms, MEMS fast steering mirrors, lenslet arrays, gimbal movers etc. We introduce the approach of a compact photonics integrated circuit consisting of power division network, optical phase array antennas and liquid crystal on silicon structure to form a laser transmitting module for a CubeSat. An Erbium Doped Fiber Amplifier provide adequate optical power output that can facilitate a baseline free-space communication link margin at 1550nm. The design parameters were tuned to achieve to minimal divergence and adequate beam steering angle, higher EIRP, high beam switching speed and tolerance of space environmental conditions. Applications are numerous and not limited to optical communication terminals on drones, aircrafts, and satellites; automotive LiDAR systems, medical and scientific instrumentation devices are also promising areas of rapid adoption and integration.

Growing interest in free-space optical communication, due to the high bandwidth and security provided by these links, has generated the necessity of designing high-performance satellite terminals. In order to develop these terminals, the optothermo-mechanical phenomena that appear in the space environment and their effect on optical communication links have to be understood in detail. A review of the opto-thermo-mechanical phenomena occurring in spaceborne terminals is presented, describing the relevance of each of them. The methods found to compute the impact on the communication performance due to opto-thermo-mechanical phenomena are collected by building the bridge between the optical and communication performance parameters. Finally, techniques available to mitigate the detrimental effects of these phenomena are classified, and the relevant research challenges are identified.
