NIST Requirements Document 950 nm tunable laser

I. Background/Purpose:

The Photonics and Optomechanics Group in Microsystems and Nanotechnology Division develops nanophotonic devices for applications in quantum sensing and position, navigation, and timing. As part of our research on nonlinear and quantum integrated photonics devices, we require a continuously tunable laser in the 950 nm wavelength band. This 950 nm tunable laser will be used in characterization and operation of microresonator optical frequency conversion and parametric oscillation devices.

II. Minimum Requirements

The Contractor shall provide a Firm Fixed Price quotation for one (1) 950 nm tunable laser. This laser must meet or exceed the technical specifications listed below. All items must be new. Used or remanufactured equipment will not be considered for award. Experimental, prototype, or custom items will not be considered. The use of “gray market” components not authorized for sale in the U.S. by the proposer is not acceptable. All line items shall be shipped in the original manufacturer’s packaging and include all original documentation and software, when applicable.

Technical Specifications:

The laser wavelength must be continuously tunable, without mode hops, from 920 nm to 990 nm or wider. The delivered product must include the necessary control electronics to set and scan/modulate the laser diode current and piezo voltage; the latter must enable >50 GHz laser frequency scans, without mode hops, and a resolution of 5 kHz or better. The laser should deliver >30 mW (with optical isolation) across its wavelength range. It should exhibit a short-term linewidth <10 kHz and integral linewidth <1 MHz. The controller must have an interactive touch screen for selecting operational modes, setting parameters, and visualizing signals at provided input ports. The laser wavelength must be tunable using a coarse motion stage, a piezoelectric motion stage, and the laser diode current. These tuning methods must be able to operate simultaneously. The laser and control electronics must meet or exceed the following specifications:

1. Mode-hop free wavelength range: 920-990 nm or wider

2. Output power: at least 30 mW across complete wavelength range and >60 mW at the optimal wavelength

3. Typical instantaneous linewidth: < 1 kHz

4. Typical integral linewidth: < 1 MHz

5. Typical short-term linewidth (5 us integration): < 10 kHz

6. Beam polarization: Linear > 100:1

7. Fiber coupling efficiency: > 50%

8. Optical isolation: > 60 dB

9. Piezo optical frequency scan range: > 50 GHz

10. Maximum wavelength scan speed: > 5 nm/s

11. Piezo modulation bandwidth: > 100 Hz

12. Diode current port modulation bandwidth: > 100 kHz

13. Locking capacity for side-of-fringe or top-of-fringe locking with two feedback channels and 30 kHz bandwidth

III. Deliverables

950 nm tunable laser

Standards of Acceptance: The NIST TPOC or COR shall review each deliverable and respond with an acceptance or request for revision email to the Contractor Point of Contact (POC) within fourteen (14) days of receipt of deliverable. This section applies to deliverables which must be reviewed and approved for acceptances (draft plans, drawings, etc.)

IV. Place of Performance All deliverables shall be delivered to NIST in Gaithersburg, Maryland in accordance with Section VI. Delivery Terms.

V. Period of Performance/Lead Time Delivery shall be within one hundred and fifty (150) days after receipt of award (ARO).

VI. Delivery Terms

Delivery shall be FOB destination and shall occur within one hundred and fifty (150) days. FOB Destination means: The contractor shall pack and mark the shipment in conformance with carrier requirements, deliver the shipment in good order and condition to the point of delivery specified in the purchase order, be responsible for any loss of and/or damage to the goods occurring before receipt and acceptance of the shipment by the consignee at the delivery point specified in the purchase order; and pay all charges to the specified point of delivery. The contractor shall deliver all Line Items to:

Kartik Srinivasan National Institute of Standards and Technology 100 Bureau Drive Stop 6811 Building 216, room E108 Gaithersburg, MD 20899-1640 VII. Inspection and Acceptance

In addition to the inspection and acceptance terms articulated in 52.212-4, the Government reserves the right to perform such performance tests and evaluations as defined below to verify specified system performance. Such tests and evaluations, if performed, shall be conducted within the environment that the system is to be operated. The Contractor has the right to be present during the tests and evaluations, if performed, at the Contractor’s expense.

The place of acceptance shall be:

100 Bureau Drive Building 216 Gaithersburg, MD 20899

VIII. Installation

Installation will be completed by NIST.

IX. Training

No in-person training is required. The vendor will provide any relevant videos, operating manuals, and other materials needed to use the equipment.

X. Warranty

The contractor shall warrant the system and provide support for a minimum of one year after receipt of the software and shall be in accordance with terms in FAR 52.212-4

XI. Payment Schedule

The Contractor shall be paid, in accordance with Net 30-day payment terms, upon receipt and acceptance of a proper invoice, in accordance with the following schedule:

1. 100% after receipt and acceptance by the TPOC of fully delivered system

2. The Government anticipates inspection will occur within two weeks of system delivery

NOTE: Partial shipments and partial invoices will not be accepted, unless other-wise requested and accepted by the Contracting Officer prior to award offer. Proposed payment schedules shall be submitted with vendor’s response to the RFQ for consideration.
