Integrated and fiber-optics have transitioned from laboratory development to practical implementation for both commercial and space applications. They are assisting to enhance the capabilities of micro-electronic systems, and in applications where it is advantageous, to overtake them. This talk will provide an overview of fiber-optic and photonic device and system development at MPB Communications, in several cases driven by the needs of space systems, but in others spun into space applications from terrestrial fiber-optic communications systems. IOSPEC, for Integrated Optical Spectrometer, was initially developed through a project with DRDC Valcartier and Christine Tremblay and her group at INO. It employs a slab waveguide integrated with a master blazed grating formed by microlithography and preferential etching in patterned mis-cut crystalline silicon. The principle advantages include a large input numerical; aperture of 0.22 and monolithic integration of the optics into a very compact and robust spectrometer system. MPBC’s Fiber Bragg Gratings were applied to sensing temperature and pressure through the Fiber Sensor Demonstrator(FSD) payload development with the Canadian (CSA) and European) ESA Space Agencies. This was launched on ESA’s Proba-2 spacecraft in Nov. 2009 and is still in operation today, more than 10 years later. Leading-edge integrated-optic component were developed in collaboration with Ecole Polytechnique through several projects with ESA and CSA to form the basis on integrated Optical micromachines. These were applied to integrated functional accelerometers and rotation sensors. More recently, MPBC fiber laser and amplifier technologies are being applied to high-capacity free-space optical data links. These technologies are being adapted to the stand-off multi-wavelength chemical lidar needs of the potential VMMO Volatile and Mineralogy Mapping Cubesat lunar orbiter with ESA, CSA, UK Space and Portugal. VMMO will also use the 1564 nm fiber-laser channel to provide a high-capacity optical data link from lunar orbit to suitable terrestrial optical ground stations.
