May 2014: NASA Awards Fibertek three Phase I SBIRs
S1.01-9773: Laser Transmitter for Space-Based Atmospheric and Oceanographic LIDAR
Under this SBIR, Fibertek will begin development of a laser transmitter designed for second-generation lidar missions but with advanced capabilities including:

  • Average output power of 50-100 Watts at repetition rates of 500-1000 Hz
  • Ten percent electrical efficiency from satellite bus power
  • Multi-line single-frequency output capability at 1064 nm, 532 nm, and 355 nm
  • Narrow linewidth output in the blue-green region, selectable between 450 and 490 nm.

These features will allow the transmitter to be used for measurements of deep subsurface ocean scattering, providing unprecedented capability for direct depth-resolved measurements of the ocean ecosystem.

S1.01-9740: Methane LIDAR Laser Technology
Under this SBIR, Fibertek will develop laser technologies to measure methane in the atmosphere. Fibertek will develop an injection-seeded Erbium-doped YAG (Er:YAG) laser transmitter, increasing the performance of an existing GSFC methane lidar SNR by 20-40 times and enabling future International Space Station (ISS) and satellite platform missions. Key innovations include:

  • Average output power >5W at 10kHz PRR
  • Direct generation of near-transform-limited single-frequency output at a 1.65nm methane absorption wavelength with appropriate linestrength for high-altitude aircraft or spaceflight measurements.
  • High reliability and compact size, weight and power (SWaP)
  • 4-8% wall plug efficiency

Z20.01-9956: 1U CubeSat Lasercom Terminal for Deep Space Communication
In this NASA SBIR-Select Phase I program Fibertek will design, optimize, and analyze a 1U CubeSat Lasercom Optical Terminal for deep-space communication, with the following target characteristics:

  • Low Size/Weight/Power (SWaP) 1U Lasercom Terminal for deep-space missions with a total power budget under 5 Watts
  • Athermalized, fiber-coupled optical telescope for lasercom transmit/receive function
  • Innovative monolithic design and fabrication of the optical assembly with large 6.5cm aperture,
  • Low power radiation-tolerant FPGA based electronics design, for a reconfigurable and highly capable processing platform
  • Use of integrated simulation & modeling tools (optical, thermal, vibration, jitter-control, etc.) for detailed design analysis, and to assist in future hardware-in-the-loop testing of critical functions to validate performance, prior to prototype build and test.
