A double ring resonator coupled laser (DR-RCL) is proposed and analyzed in this letter.
Benefiting from the uniform peak transmission, narrow bandwidth and other superior …

The paper describes the design of a super-structure-grating distributed Bragg reflector (SSG-
DBR) laser for broad quasicontinuous wavelength tuning with stable single-mode operation …

A theory of the dispersion in the Moiré gratings is developed and it is shown that the group
velocity of light in them can be reduced by up to three orders of magnitude. A conceptual …

A 64 channel arrayed-waveguide multiplexer with 0.4 nm (50 GHz) channel spacing at 1.55
µm has been fabricated using SiO2/Si waveguides. The authors obtained a crosstalk of less …

This paper presents an overview of fiber Bragg gratings (FBGs) fabrication principles and
applications with emphasis on the chirped FBG used for dispersion compensation in high …

We have demonstrated a semiconductor optical amplifier and electroabsorption modulator
monolithically integrated with a novel dual-waveguide spot-size converter at the input for low …

Fiber Bragg gratings with phase-only superstructure (" sampling") are shown to greatly
increase the reflectivity of large channel count designs. Grating fabrication is facilitated by …

To overcome the limitation of the small tuning range of 1.3-µm-wavelength distributed Bragg
reflector (DBR) lasers using the carrier-plasma effect, we designed a DBR structure with …

We demonstrated numerically that both the chromatic dispersion and the dispersion slope
can be compensated by using purely phase-sampled superstructure fiber Bragg gratings …

A new method of modulating the coupling coefficient along the waveguide is proposed. The
effect of our method, which uses a nonperiodic sampled grating, is demonstrated both …
