CMOS photodiodes for narrow linewidth applications
2011 IEEE SENSORS Proceedings, 2011In recent years CMOS image sensors have gained a major market share for general imaging applications. However, when standard CMOS image sensors are employed in applications that require the detection of light with a very small spectral width, like 3D-time-of-flight imaging or other applications with laser light illumination, problems arise, that are ...

Tunable fiber laser with narrow linewidth
2016 Photonics North (PN), 2016We demonstrate a narrow linewidth tunable fiber laser based on a tunable fiber Bragg grating, a linear or ring cavity fiber laser and a piece of non-pumped active fiber setup.

Narrow linewidth UV sources at 257nm
SPIE Proceedings, 2017We describe and compare the performance of two types of compact, passively Q-switched Yb:YAG 1030nm lasers and their use for 257nm fourth harmonic generation (FHG). In the first implementation, an end-pumped Yb:YAG laser produced a 250μJ pulse train with an average power at 1030nm of 3.6W. Using a 10mm LBO crystal (70% doubling efficiency), followed by

A study of narrow linewidth Li-ferrite
IEEE Transactions on Magnetics, 1980Using conventional ceramic procedure and cheap raw materials, we have succeeded in preparing narrow linewidth polycrystalline Li-ferrites with the chemical formula: Li 0.5(1-x+y) Zn x Ti y Fe 2.5-0.5(x+3y)-z Mn z O 4 in the region of 0.15 and observed the growth condition of the grains.

Narrow-linewidth and tunable parametric oscillator
CLEO 2024We present a tunable coherent oscillator based on parametric gain. It is realized through self-injection locking one comb line of a Kerr microcomb. Sub-Hertz intrinsic linewidth and 20nm tuning range are achieved.

Narrow linewidth tunable semiconductor laser
2016 Compound Semiconductor Week (CSW) [Includes 28th International Conference on Indium Phosphide & Related Materials (IPRM) & 43rd International Symposium on Compound Semiconductors (ISCS), 2016A full-C band tunable laser equipped with an air-gap suspended waveguide structure for efficient thermal heater tuning is described. It is shown that the monolithic tunable laser can simultaneously meet the requirements for the output power, side-mode suppression ratio, and spectral linewidth for 16-QAM coherent communication system.

Narrow linewidth on-chip III-V/TFLT laser
Optics LettersWe report a narrow-linewidth laser based on thin-film lithium tantalate (TFLT). The laser is composed of an InP reflective semiconductor optical amplifier gain chip hybrid integrated with a TFLT waveguide external cavity cladded with a silicon oxide extended Bragg grating. The single-frequency laser device achieves an on-chip output
