based on hybrid integration of a III-V/LNOI laser. We exploit the laser self-injection locking effect by directly edge-coupling an InP distributed feedback (DFB) laser with a LiNbO3racetrack resonator. The bulk and surface scattering

it has a unique design featuring a DFB laser which extends its lifetime. Instead of requiring replacement every few years, Pinpoint will last for more than ten years, usually outliving the lifetime of the system itself. This reduces maintenance requirements, as well as replacement and service...
DFB-LD Measurements The DFB-LD is a single-spectrum semiconductor laser diode. It is commonly used in high-speed, long-distance communications applications due to its low optical-signal wavelength variation and small optical-signal waveform deterioration. The following items are measured for DFB-LD ...
In the experiment, DFB laser array with single-channel and four-channel are used to demonstrate the proposed algorithm. Experiments results show that the single-channel's error is below 5 pm, four-channel's is below 2 pm, strain and algorithm results show good linearity....
We assume that fiber non-linearity reduces the improvement obtained by XTC because the neighboring crosstalk does not dominate the Q-impairment in the higher power region. In high power region where fiber non-linearity impairs the signal quality, we already confirmed that NLC improves the Q-factor...

The coefficients of determination R² of 0.9999 and 0.9984 validate the linearity of both calibration curves, respectively. The photoacoustic amplitude and, thus, the sensitivity is significantly lower for the measurement with acetone in nitrogen. This phenomenon is attributed to oxygen acting as a ...
