“…Similar to other tunable diode lasers, the slotted laser uses the Vernier effect to extend the tuning range associated with limited refractive index change. The Vernier effect is a well known technique [12]- [14] for extending the tuning range of widely tunable lasers containing two reflectors with a different grating period, causing a slightly different peak spacing in the reflection spectrum. Lasing occurs when peaks of both sections overlap, so by slightly changing the refractive index of one section two other peaks that are further away will overlap and tuning over a wide wavelength range is obtained.…”

Enhanced mode selection is facilitated by incorporating compact two dimensional photonic crystal gratings into FabryPerot lasers. The gratings are etched directly through the active layer and interact strongly with the guided mode. A high mode-selectivity 2D grating which is significantly wider than the ridge waveguide structure is investigated. The mode selectivity for the structure is -37 dB. The enhanced selectivity afforded by the broad 2D grating is attributable to a novel and robust photonic bandgap mechanism: transverse mode beating.

“…Sampled fiber gratings (SFGs), known as special superstructure fiber Bragg gratings, have been widely researched and used in the field of multi-parameter sensing, optical filters, and multi-wavelength laser [1][2][3][4][5][6]. The SFG possesses special superstructure refractive index distribution, which is formed by multiple sub-gratings in a regular arrangement [1].…”

Sampled fiber grating is a special superstructure fiber Bragg grating with a wide range of applications in many fields. In this work, based on drawing tower in-line fabrication system, a new preparation method of the sampled fiber grating is proposed and experimentally demonstrated. Experimental result shows that the obtained sampled fiber gratings possess dense reflection spectra, with a minimum reflection peak interval of only 0.09 nm. This method exhibits promising application prospect in the fabrication of the high-quality sampled fiber grating. On the other hand, the spectral characteristics of the sampled fiber grating are analyzed when the sub-grating is affected by the external physical quantities such as, in this paper, strain. Wavelength shift and intensity change in the reflection peak of the spectra indicate that the grating is affected differently by micro strains, due to the different spatial positions along the axis of the sampled fiber grating. This work is aimed at exploring the potential applications of the sampled fiber grating in quasi-distributed micro-area sensing with the millimeter level.
