Optical devices using an external cavity semiconductor laser

The investigation of the nonlinear dynamics of a semiconductor laser based on nonlinear optical loop mirror (NOLM) feedback using Ge doped optical fiber was carried

Vertical cavity semiconductor optical amplifiers (VCSOAs) structures are based on Fabry Perot (FP) method to design optical gain and bandwidth gain to be operated in

Using a single initial laser diode, considering that the distortion due to subsequent optical components is negligible (e.g. no significant chirp is introduced) because they

We combined an external cavity diode laser with noise-immune cavity-enhanced optical heterodyne molecular spectroscopy (NICE-OHMS) using current modulation.. The system was

An output of 1 W at 850 nm has been demonstrated from an optically in-well-pumped VECSEL. This was achieved using a fiber-coupled laser diode emitting at ⬃ 800 nm and reflecting

Wireless optical links transmit an optical intensity modulated in response to an input laser diode electrical current signal.. Generally the optical channels are

We have numerically analyzed the degree of unpredictability of the hyperchaotic time traces generated by the output of a semiconductor laser subject to delayed optical feedback

In this paper, a FMCW laser source based on self-injection locked commercial distributed feedback (DFB) laser diode (LD) coupled with high-Q SiN micro-ring resonator (MRR)
