Title Development of A Silicon Membrane-based Multi-pixel Hot Electron Bolometer Receiver Type Conference Article
Year 2017 Publication IEEE Trans. Appl. Supercond. Abbreviated Journal IEEE Trans. Appl. Supercond.
Volume 27 Issue 4 Pages 6
Keywords Multi-pixel, HEB, silicon-on-insulator, horn array
Abstract (down) We report on the development of a multi-pixel

Hot Electron Bolometer (HEB) receiver fabricated using

silicon membrane technology. The receiver comprises a

2 × 2 array of four HEB mixers, fabricated on a single

chip. The HEB mixer chip is based on a superconducting

NbN thin film deposited on top of the silicon-on-insulator

(SOI) substrate. The thicknesses of the device layer and

handling layer of the SOI substrate are 20 μm and 300 μm

respectively. The thickness of the device layer is chosen

such that it corresponds to a quarter-wave in silicon at

1.35 THz. The HEB mixer is integrated with a bow-tie

antenna structure, in turn designed for coupling to a

circular waveguide,

Title Heterodyne detection at near-infrared wavelengths with a superconducting NbN hot-electron bolometer mixer Type Journal Article
Year 2014 Publication Opt. Lett. Abbreviated Journal
Volume 39 Issue 6 Pages 1429-1432
Keywords HEB, zebra, IR, infrared
Abstract (down) We report on the development of a highly sensitive optical receiver for heterodyne IR spectroscopy at the communication wavelength of 1.5 μm (200 THz) by use of a superconducting hot-electron bolometer. The results are important for the resolution of narrow spectral molecular lines in the near-IR range for the study of astronomical objects, as well as for quantum optical tomography and fiber-optic sensing. Receiver configuration as well as fiber-to-detector light coupling designs are discussed. Light absorption of the superconducting detectors was enhanced by nano-optical antennas, which were coupled to optical fibers. An intermediate frequency (IF) bandwidth of about 3 GHz was found in agreement with measurements at 300 GHz, and a noise figure of about 25 dB was obtained that was only 10 dB above the quantum limit.

Title 10.6 μm heterodyne receiver based on a superconducting hot-electron bolometer mixer and a quantum cascade laser Type Journal Article
Year 2019 Publication AIP Advances Abbreviated Journal AIP Advances
Volume 9 Issue 7 Pages 075307
Keywords NbN HEB mixers, QCL, IR
Abstract (down) We report on the development of a heterodyne receiver at mid-infrared wavelength for high-resolution spectroscopy applications. The receiver employs a superconducting NbN hot electron bolometer as a mixer and a room temperature distributed feedback quantum cascade laser operating at 10.6 μm (28.2 THz) as a local oscillator. The stabilization of the heterodyne receiver has been achieved using a feedback loop controlling the output power of the laser. Improved Allan variance times as well as a double sideband receiver noise temperature of 5000 K and a noise bandwidth of 2.8 GHz of the receiver system are demonstrated.

Title Optimization of contra-directional coupler based on silicon nitride Bragg rib waveguide Type Conference Article
Year 2018 Publication J. Phys.: Conf. Ser. Abbreviated Journal J. Phys.: Conf. Ser.
Volume 1124 Issue Pages 051048
Keywords Bragg waveguide, Si3N4
Abstract (down) We report on the development and fabrication of a contra-directional coupler based on the Bragg waveguide on Si3N4 platform. Transmitted and reflected by the contra-directional coupler spectra were measured. The reflected spectra exactly matches the one notched by the main channel of the coupler. Losses are about 3dB, coupling to the directing branch of the coupler is practically lossless. FWHM of the transmitted (reflected) spectra is 3.46 nm.

Title CWDM demultiplexer using anti-reflection, contra-directional couplers based on silicon nitride rib waveguide Type Conference Article
Year 2019 Publication J. Phys.: Conf. Ser. Abbreviated Journal J. Phys.: Conf. Ser.
Volume 1410 Issue Pages 012179
Keywords coarse wavelength-division multiplexing, Si3N4 rib waveguide
Abstract (down) We report on the development and fabrication of a 9-channel coarse wavelength-division multiplexing for telecommunication wavelengths (1550 nm) using anti-reflection contra-directional couplers, based on silicon nitride (Si3N4) rib waveguide. The transmitted and reflected spectrum in each channel of the demultiplexer were measured. The average full width at half maximum of the transmitted (reflected) spectra is about 3 nm.
