We report the first experimental realization of four-channel DFB laser array with equivalent phase shift (EPS) based on the reconstruction-equivalent-chirp (REC) technique for CWDM systems. OCIS codes: (140.0140) Lasers and laser optics; (140.5960) Semiconductor lasers

Experimental demonstration of a multi-wavelength distributed feedback semiconductor laser array with an equivalent chirped grating profile based on the equivalent chirp technology.

We report, to the best of our knowledge, the first realization of a multi-wavelength distributed feedback (DFB) semiconductor laser array with an equivalent chirped grating profile based on equivalent chirp technology. All the lasers in the laser array have an identical grating period with an equivalent chirped grating structure, which are realized by nonuniform sampling of the gratings. Differ...

DFB laser monolithically integrated with amplifier array

Experimental demonstration of distributed feedback semiconductor lasers based on reconstruction-equivalent-chirp technology.

In this paper we report, to the best of our knowledge, the first experimental realization of distributed feedback (DFB) semiconductor lasers based on reconstruction-equivalent-chirp (REC) technology. Lasers with different lasing wavelengths are achieved simultaneously on one chip, which shows a potential for the REC technology in combination with the photonic integrated circuits (PIC) technolog...

Chirp Compensation in Active Mode-Locked Semiconductor Diode Laser Using a DFB

This thesis investigates the possibility of canceling chirp in an actively modelocked semiconductor laser using a DFB structure. The chirp is caused by the nonlinearity of the diode, namely, the line-width enhancement factor, a. The mode-locking equations are formed, and the postulated solution is a gaussian pulse shape. The diode is modeled primarily using the rate equations for carrier and ph...
