Photonic Bolometer and Broadband High-Absorption Photonic Bolometry

NIST Inventors
Nikolai Klimov , Nathan A Tomlin and Chris Yung
A photonic bolometer includes: a photonic chip; a weak thermal link; a thermally-isolated member, and the weak thermal link thermally isolates the thermally-isolated member from the photonic chip; a photonic temperature sensor; a chip waveguide in optical communication with the photonic temperature

An Optical Readout for a Thermal Detector Array

NIST Inventors
Nathan A Tomlin
The invention is a readout method for a novel detector array designed to measure mm-wave, submm, THz, and/or IR. The main components are a waveguide, waveguide splitters, waveguide-coupled resonator pixel array (primary), and a secondary detector array.

Recessed Carbon Nanotube Article and Method for Making Same

NIST Inventors
Chris Yung , Nathan A Tomlin and Dan Schmidt
A microbolometer structure including carbon nanotubes, a substrate (silicon, alumina, etc.) with an array of micromachined wells/holes/pockets, a weak thermal link (membrane or legs) at the base of each well/hole/pocket, a protection layer bonded to substrate over the wells for subsequent back side
A disk-shaped device is smaller than the half-dollar coin underneath it.

Smart Mirror

NIST Inventors
Alexandra (Aly) Artusio-Glimpse , John H. Lehman , Michelle Stephens , Nathan A Tomlin and Paul A. Williams
The Smart Mirror is a device that accurately measures the power of laser sources without disturbing the laser beam. This is a promising technology for accurate monitoring of output power in industrial lasers that allows power measurement during the laser’s performance of its routine operations. Such
Clockwise from upper left: bolometer for optical fiber power measurement operates at 4K, bolometer for space-based measurement of solar spectral irradiance, operates at room temperature; bolometer for continuous wave, visible/near infrared laser power measurement, operates at room temperature; bolometer for fast far infrared power calibration, operates at 4K.

NIST Radiometer

NIST Inventors
John H. Lehman and Nathan A Tomlin
This advanced radiometer is composed of a substrate, a radiation absorber placed on the substrate to absorb radiation, a thermal component placed on the substrate to change electrical resistance in response to a change in temperature of the radiometer, and a thermal link to connect the radiometer to
