Sample Task TITLE: High Speed Optical Receiver

I. BACKGROUND INFORMATION

The NIST Photoelectronics Engineering Division (Hypothetical Division for the purpose of this Task Order) is responsible for providing the best available measurements of optical properties. The Division develops and maintains high accuracy instruments and apparatus for a wide range of materials, component, and device measurements. The measurements extend over wide ranges of power, wavelength, and temperature. The instrumentation is utilized to gather technically important data that are critical to industry. The experimental work is closely integrated with the theoretical work carried out in the Division. The Division’s efforts are leveraged by collaboration with universities, industrial consortia, and standards organizations.

II. SCOPE OF WORK

a. OBJECTIVES/PURPOSE

This procurement requires the development and demonstration of a very high speed photodiode receiver for use as a calibrated pulse generator. Deliverables shall consist of an experimental design, breadboard prototype, and a bill of materials required to potentially have the apparatus manufactured in the future.

b. GENERAL:

NIST has standard high-speed receivers used for providing pulse measurement calibrations. These receivers must have stable properties over a 20 to 30 degrees Celsius temperature range. NIST also uses a fiber laser to produce ~ 1ps pulses with 10 MHz repetition rate at 1550 nm with approximately 20 mW of output power to test these receivers. NIST seeks assistance in characterizing existing photodiode receivers, and developing the next generation of high speed photodiode receivers, with a study that includes trade-offs between several key parameters described below.

c. SPECIFIC REQUIREMENTS:

Task 1: Mandatory Orientation and Safety Training

The Contractor must attend the mandatory orientation and safety training at NIST, Gaithersburg prior to commencing work on this project.

Task 2: Temperature Testing of Receiver Performance

The contractor is required to write LabView code to automate NIST-provided temperature testing of receiver performance using a computer-controlled heater and thermometer system. The contractor shall use the NIST laser source and test equipment (listed in the Available Tools and Equipment section below) to measure the following properties for two present-generation receivers to be provided by NIST over the 20 to 30 degrees Celsius temperature range:

· pulse width (FWHM) and pulse shape

· pulse width stability over 48 hour temperature soak tests

· pulse width variation during temperature excursions of 2 degrees Celsius per hour

· output impedance over frequency over the temperature range Task 3: Preliminary Design of New Generation Receiver

The Contractor must develop a preliminary design of a new generation of receiver (photodiode/amplifier) capable of repeatably measuring picosecond laser pulses from the 1550 nm fiber laser. The next generation receiver must have the following specifications:

· Single-mode optical fiber input

· Nominally 50 ohm output via 3.5 mm coaxial connectors, from 0 to 50 GHz, with +/- 0.5 dB flatness. The design must include the ability to provide options for varying the output impedance (for example, 100 ohm and 25 ohm versions, and different frequency variations of output impedance.

· Impulse response < 10 ps FWHM with output pulse with a design that allows varying output voltages (for example 100 µV or 10 mV) using NIST existing laser sources.

· Pulse output and output impedance repeatable must be within 1 percent over a 20 to 30 degrees Celsius temperature range.

Task 4: Prototype New Generation Receiver The contractor shall construct a breadboard prototype using NIST-supplied parts and equipment to test the receiver design tradeoffs among various key parameters. The key parameters, at a minimum, include the following: output pulse width, transimpedance, output impedance, and output impedance flatness with frequency. Based on this work, the contractor shall provide the prototype, a modified preliminary receiver design and a bill of materials. A partial list of equipment available for use is provided below.

Task 5: Final Design Based on Breadboard Testing

The Contractor shall complete the final design, based on any potential changes and comments made by the Government based on the preliminary design and on the breadboard testing of tradeoffs. The final design and bill-of-materials must be provided to NIST.

Task 6: Monthly Status Reports

Monthly status reports must be provided to the NIST task order contact/COR and NIST PM, identified within the task order, by the 10th day of the next month. The status reports, at a minimum, must address the status of each deliverable, which deliverables have been completed under the task order, outstanding deliverables, any delays, reason for delays and risk/issue management.

III. PERIOD OF PERFORMANCE

The period of performance shall not exceed one year.

IV. PLACE OF PERFORMANCE

The place of performance will be NIST, 100 Bureau Drive, Gaithersburg, Maryland 20899. The contractor will have access to a laboratory equipped with lasers, instrumentation, and data acquisition software and hardware.
