Contract Opportunity

***THIS IS A COMBINED SOURCES SOUGHT NOTICE AND NOTICE OF INTENT TO SOLE SOURCE***

The purpose of this sources sought notice is to conduct market research and identify potential sources of commercial products/services that satisfy the Government’s anticipated needs. If no alternate sources are identified, the Government intends to issue a Sole Source Award to Toptica Photonics Inc, 1120 Pittsford Victor Rd, Pittsford, NY, under the authority of FAR 13.106-1(b)(1)(i). The North American Industry Classification System (NAICS) code for this acquisition is 334516, Analytical Laboratory Instrument Manufacturing.

BACKGROUND

As part of the CHIPS R&D Program, the National Institute of Standards and Technology (NIST) Physical Measurement Laboratory (PML), Microsystems and Nanotechnology Division (MND), works on sensing methods using micromechanical resonators to perform critical physical measurements for measurands including acceleration, pressure, sound, and mass. For this procurement, the MND require a tunable laser that will used in mass sensing experiments for atomic layer deposition processes used widely in semiconductor manufacturing.

The MND requires a tunable diode laser operating around a wavelength of 780 nm to perform laser interferometry on microwave acoustic devices. These devices are being used to characterize atomic layer deposition (ALD) processes, providing high time and mass resolution for the deposition dynamics of these processes. This is part of a larger effort to perform high-fidelity process metrology for ALD and use the resulting data sets to build a digital twin of ALD processes. ALD is essential for state-of-the-art semiconductor manufacturing, where it is used to create electrical isolation layers in transistors that are a countable number of atoms thick. The resulting ALD digital twin will allow U.S. manufacturers to optimize process conditions using virtual models, thereby increasing fabrication yield and pushing towards the fundamental limits of transistor performance.

Implementing the laser interferometer in the near term is essential to the success of the project because it provides the ultimate sensitivity for detecting the deposition of single atomic layers at high measurement rates. Fabrication of the microwave acoustic resonators will be completed within the fourth quarter of FY25. The laser must be purchased in early FY26 to meet the milestone of demonstrating our new measurement method with interferometric detection by the end of FY26.

NIST is seeking information from sources that may be capable of providing a solution that will achieve the objectives described above, in addition to the following essential requirements:

Line Item 0001: Tunable 780 nm laser

Quantity: 1

Key Capabilities

The tunable laser must include the following:

1. A laser head design based on a tunable external cavity with a laser diode. The laser head must include a polarization maintaining fiber output and an optical isolator to protect the laser diode from reflected laser power. The laser wavelength must be tunable using a coarse adjustment stage, a piezoelectric actuator, the laser diode current, and the laser diode temperature, where these tuning methods must be able to operate simultaneously. The coarse adjustment stage for tuning must be capable of being upgraded with a precision motor control for hands-free tuning.


2. A laser controller with power and control electronics for tuning the laser using the diode temperature, the diode current, and external cavity piezoelectric actuator methods. The controller must have an interactive screen for selecting operational modes, setting parameters, visualizing optical resonances of an optically interrogated cavity as the laser tunes, and selecting resonances for locking. The controller must be fully digital with 24 bit inputs for the best control resolution.


3. The laser controller must include laser locking capabilities, including locking to the “top of fringe” and ‘side of fringe” methods for an optical resonance or atomic absorption line. The controller must include proportion-integral-derivative (PID) controllers and algorithms for implementing laser locks. Further, the controller must have a signal generator for modulation schemes and an integrated lock-in amplifier for implementing frequency-modulated locking methods.

2. Mode-hop free tuning range: ≥ 20 GHz


3. Maximum power at 780 nm: ≥ 35 mW at the exit of a polarization maintaining optical fiber connected to the laser’s fiber coupled output

NIST conducted market research from April to December 2025 by performing internet searches, reviewing product literature, and speaking with vendors to determine what sources could meet NIST’s minimum requirements. The results of that market research revealed that only Toptica Photonics Inc (UEI: EYC4JKCBA7J9) appears to be capable of meeting NIST’s requirements.
