medical instruments and telecommunications systems
• Optical assemblies for collection and management of laser light through fiber optics for
industrial and laser instrumentation
“Over the course of the past year, our management team and board members have worked together
on a comprehensive analysis of our products, strengths, market position and market needs,” said Jim
Gaynor, CEO of LightPath Technologies. “We are in a position now to leverage the manufacturing
technology and optical expertise we’ve developed over the last 20 years into a specific set of
significant growth applications and industries. We are particularly excited about our new
opportunities in the infrared market. Applications of infrared and thermal imaging technology have
grown dramatically over the last ten years into various markets including industrial inspection,
automotive safety, chemical and biological sensing and security and surveillance.”
Mr. Gaynor went on to say, “Cost is now a major barrier to further expansion into mission‐critical
defense and high‐volume commercial applications. LightPath has a process that when completely
developed will reduce optics cost by 35‐40% or more. This should have a significant impact on the
market and our business.”
“In addition to the outlook for emerging applications like infrared, which is now close to a $5B

Corner Cube Retroreflector (CCR) for Free Space Optics (FSO)
Piezoelectrically operated MEMS corner cube retroreflector for optical communications
Research Paper -- A bulk-micromachined corner cube retroreflector (CCR) was designed and fabricated for free-space optical communications with ultra-low voltage operation and negligible power consumption. The proposed CCR was comprised of a bulk-micromachined vertical mirror which has two mutually orthogonal reflective surfaces and a horizontal mirror with piezoelectric actuator.The fabricated vertical and horizontal mirrors have sizes of 300 µm × 300 µm and 150 µm × 150 µm, respectively. The vertical mirror was fabricated using a double silicon-on-insulator wafer and the anisotropic wet etching of a (1 1 0) silicon wafer.
The horizontal mirror was comprised of two supporting and one actuating lead zirconate titanate (PZT) cantilevers. The supporting cantilevers were utilized for the accurate angular alignment of the mirror by balancing and isolating the residual stresses occurring in the PZT cantilevers.
The bottom-actuated mirror exhibited an angular displacement of 1.37° at an applied voltage of 5 V. The fabricated CCR exhibited a good angular misalignment of less than 0.35° and switching characteristics with an off-to-on-state transition of 163 µs and on-to-off-state transition of 276 µs at a rectangular input voltage and switching frequency of 10 V and 1 kHz, respectively.
The fabricated CCR also exhibited a cutoff frequency of 2.5 kHz and could be digitally modulated up to about 5 kb s−1.

Flow Cytometer that uses Fiber Optic Sensor Technology
Microflow is a portable a flow cytometer that uses fiber optic sensor technology to overcome limitations in industry standard flow cytometers due to high power consumption and cumbersome form factor. This technology allows astronauts to monitor their immune health and detect a variety of health conditions during space missions.
It uses advanced fiber optic sensor technology to create a flow cytometer in a portable form factor without sacrificing accuracy over traditional fluorescent spectrum beam and sensor systems. The fiber optic sensors allow detection, counting, and physical and chemical characterization of each individual particle present in a microscopic sample of organic fluid. Advances in laser micromachining techniques have allowed Institut National d'Optique (INO) to etch flow cells into fiber optic sensors allowing them to miniaturize the hardware required to perform fluorescent spectrum and optical scattering analysis.
Key Features:
- Full, on-site operation with automated flow cytometry analysis
- Small, portable form factor
- Low power requirements compared to traditional flow cytometers
The flow cytometer was developed from a University of Montreal prototype by INO with funding from the Canadian Space Agency (CSA) to provide low power, low footprint technologies for on-site advanced medical analytics in space operations. The portability of the device makes it relevant for military and emergency response applications, as well as for field medicine and research.

Research Paper - Distributed Flow Sensing Using Optical Hot-Wire Grid
An optical hot-wire flow sensing grid is presented using a single piece of self-heated optical fiber to perform distributed flow measurement. The flow-induced temperature loss profiles along the fiber are interrogated by the in-fiber Rayleigh backscattering, and spatially resolved in millimeter resolution using optical frequency domain reflectometry (OFDR).
The flow rate, position, and flow direction are retrieved simultaneously. Both electrical and optical on-fiber heating were demonstrated to suit different flow sensing applications.
