Prominent World Class Laboratories Use Nicslab's Products for Forefront Research in Photonics

Products of Nicslab have been utilized by several prominent laboratories in the world for many photonic use cases. The world’s top researchers from three (3) different groups have mentioned Nicslab in their four (4) papers:

  • The first hybrid-integrated diode laser in the visible light spectra [1]

In this paper, Franken et al. from the University of Twente, the Netherlands; LioniX International, the Netherlands; and the University of Münster, Germany presented for the first time a hybrid-integrated diode laser in the visible light spectra. Nicslab XPOW-8AX-CCvCV was used to supply the chromium-based resistive heaters in this diode laser.

Figure 1. Schematic of the hybrid laser. The chip contains two sequential microring resonators that form a Vernier filter within a loop mirror. Directional couplers are indicated by red arrows. Heaters (depicted in yellow) are placed on the MRRs, on the phase section, and near the output Y-junction. All heaters' currents and voltages are supplied by Nicslab XPOW-8AX-CCvCV [1].

  • Ultralow-loss compact silicon photonic waveguide spirals and delay lines [2]

Hong et al. from Zhejiang University, China proposed a low-loss and compact silicon photonic waveguide spiral consisting of single-mode input/output waveguides, two (2) bent waveguide tapers, two (2) broadened Archimedean spiral waveguides, and a tapered Euler-curve S-bend in the middle. To realize the 10 binary-delay stages, 11 2 x 2 Mach-Zehnder (MZ) switches and 10 waveguide spirals were used. The MZ switches were switched thermally by heating their micro-heaters controlled by Nicslab XPOW-40AX-CCvCV-U.

  • An all-photonic, dynamic device for flattening the spectrum of a laser frequency comb for precise calibration of radial velocity movements [3, p.], [4]

A group of researchers from California Institute of Technology (Caltech), USA; Université Côte d’Azur, France; Bright Photonics, the Netherlands; National Aeronautics and Space Administration (NASA), USA; and the Aerospace Corporation, USA led by Nemanja Jovanovic created a novel low-cost all-photonic spectrum flattener of a laser frequency comb (LFC). Nicslab XPOW-120AX-CCvCV-U was used to drive 20 thermo-optic phase modulators (TOPMs) and 20 MZ interferometers (MZIs) simultaneously via a computer. Nicslab M6 Multiconnector was also used to connect the pins of the controller to the printed circuit board (PCB) and the device under test (DUT).
