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
The source also has an instantaneous coherence length of >1 m and a linearity ≤ ±0.5 pm root mean square without the need for an external k-clock30. The sweep rate of the laser can be adjusted from 10 kHz to 200 kHz, and for this application, we set the sweep rate...
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 ...
The main devices adopt DFB low-noise, narrow linewidth, continuous-wave lasers with the thermoelectric cooling device made in JDSU CATV high linearity external modulator. Because of the international brand adoption of key components and our company system optimization control technology, SN...
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 ...
(e.g., due to pixel non-linearity or the limited bit depth of the camera pixels), or through the optical compression process described in this work (e.g., due to laser intensity noise, environmental variations in theTmatrix, or simply shot noise at the detection stage). To simulate the...
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...
FIG. 1 shows a conventional direct detection 10 Gb/s optical transmission system100. At the transmitter side, the data are amplified through a modulator driver (MD). The amplified data modulate a distributed feedback (DFB) laser signal by an electro-absorption modulator (EAM), which are usuall...
