- Description
- AMENDMENT 0001 The Request for Information is hereby amended to make editorial changes; Question marks are hereby deleted. This is a REQUEST FOR INFORMATION. THIS IS NOT A REQUEST FOR PROPOSALS IT IS FOR MARKET RESEARCH PURPOSES ONLY. The National Institute for Standards and Technology (NIST) is requesting information from Contractors on robust, high repetition rate pulsed laser pumps for production of maximally entangled photon pairs by Spontaneous Parametric Down-Conversion (SPDC). Submissions addressing available information/technology, or adaptations thereof, as well as technical comments on pumps meeting some or all of the specifications identified herein are being requested. Submissions shall include, but are not limited to, product literature, technical data, and/or adaptation schemes. Information on the Contractors experience in building the same or similar equipment, and the proposed availability of equipment is also requested. Contractors shall identify their business size, (small, small-disadvantaged, hub-zone, large etc.) in accordance with North American Industry Classification System (NAICS) Code 334516, Analytical Laboratory Instrument Manufacturing; the Small Business Size Standard is 500 employees. If the equipment is manufactured by other than the respondent, please provide business size information on the manufacturer as well. Responses to this notice must be sent to the National Institute of Standards and Technology, Acquisition Management Division, Attn: Carol A. Wood, Contract Specialist, 100 Bureau Drive, Mail Stop 1640, Gaithersburg, MD 20899-1640. Submission must be received by 3:00 p.m. local time on January 31, 2005. Original submissions are required. Specifications for a Pulsed Laser as an Entangled Photon Source Pump NIST has a need for robust high repetition rate pulsed laser pumps for production of maximally-entangled photon pairs by Spontaneous Parametric Down-Conversion (SPDC). There are two distinct entangled photon pair wavelength ranges of interest. With this and respecting that summed energies of the SPDC photon pair must equal the energy of the pump photon, constraints on corresponding pump wavelengths are determined. The first range of interest permits optimal detection of polarization-entangled photons through the atmosphere with a Si Avalanche Photodiode (APD). Si APD has near-peak detection efficiency in the range of 550-810 nm and the preferred atmospheric transmission range is 740-810 nm (peaking at 770 nm). The desired pump wavelength range is 310-410 nm, with the understanding that resulting SPDC wavelengths should avoid several atmospheric absorption lines in the range mentioned above (see fig 5 of Nordholt, Jane E., Richard J. Hughes, George L. Morgan, Charles G. Peterson, Christopher C. Wipf ?Present and Future Free-Space Quantum Key Distribution? Free-Space Laser Communication Technologies XIV, G. Stephen Mecherle, Editor, Proceedings of SPIE Vol. 4635 (2002), pp 115-126, LA-UR-01-6817). Thus at least one of the down-converted photon pair must be within the preferred atmospheric transmission window (740-810 nm) and the other photon should be in the Si APD detection window (550-810 nm). Pumps for degenerate entangled photon pairs are preferred (both within 740-810 nm range). The other range of interest corresponds to production of time-bin entangled pairs at the telecom wavelength of 1310 nm. Allowable ranges are approximately 1280 to 1330 nm, and thus corresponding permissible pump ranges are 640 to 665 nm. For example, a 655 nm pump would produce degenerate 1310 nm photon pairs. Nondegenerate SPDC generation with one photon near the 1310-nm telecom wavelength is also acceptable. An entangled pair consisting of a photon in the 1280-1330 nm range and a photon in the Si APD detection range can be produced using a pump wavelength in the range of 385-500 nm. Although alternative solutions are not precluded, particular attention will be given to diode and fiber based constructions. NISTs requirements for these pump lasers are as follows: Average power/Pulse energy we require a minimum of 500 mw of average power; within the 10 MHz to 1 GHz repetition rate range requirement, we prefer higher energy per pulse with a goal of 50 nJ/pulse; Laser wavelength fixed in the range of 310 to 410 nm (first priority) or 385 to 500 nm or 640 to 665 nm (second priority); Laser bandwidth less than/equal to 0.05 nm; Wavelength stability/tolerance less than 10% of 0.05 nm; Spatial mode a minimum of 500 mW in TEM00 (this is defined as the amount of power that can be coupled into a single mode fiber.); Pulse duration less than or equal to 0.5 ns; Rep rate greater than or equal to 10 MHz; Duty factor less than or equal to 10% (this becomes a factor for rep rates above 200 MHz); Power stability fluctuations less than or equal to 5%; Pointing stability fluctuations less than or equal to 10% of beam divergence; Polarization purity/ stability greater than 100:1; Timing jitter with respect to trigger less than 10% of pulse duration; Physical size compactness desirable, entire system including electronics must fit in a standard 19 inch instrument rack ca. volumes of 18 inches x 24 inches x 3.5 inches or 18 inches x 9 inches x 10inches power consumption less than 10 W target (100 W max) wall-socket power; System can employ harmonic generation to generate pump wavelengths; Turnkey system operation, no user serviceable parts; Output may be fiber pigtailed. NIST is most interested in pump technology that promises straightforward extension to both the atmospheric (Si Detection) and telecom interests. In the absence of a system meeting both needs, the Si detection application is preferred.
