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...
متن کاملExperimental 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...
متن کاملSelf-injected semiconductor distributed feedback lasers for frequency chirp stabilization.
It is well known that semiconductor distributed feedback lasers (DFB) are key devices for optical communications. However direct modulation applications are limited by the frequency chirp induced by current modulation. We demonstrate that a proper external control laser operation leads to chirp-to-power ratio (CPR) stabilization over a wide range of modulation frequencies as compared to the fre...

The inductance L of the laser discharge shows an abrupt high peak which is attributed to the temporary plasma constriction [4]. This is due to the attractive electromagnetic forces (Laplace force) because of the parallel motion of the electrons. The following expansion of the plasma is caused by the finite time required for the electric field to penetrate into the plasma. This is due to the wel...

Photograph of a mechanically flexible 2D-DFB laser made from the conjugated polymer MeLPPP. The laser is optically pumped well above the threshold for amplified spontaneous emission. The complex far-field emission pattern (blue-green) results from a large detuning between the resonance wavelength and the gain maximum. • A nearly diffraction limited surface emitting conjugated polymer laser util...
