High efficiency coupling of light from a ridge to a photonic crystal waveguide.

چکیده
We present theoretical and experimental demonstration of two designs to achieve group velocity insensitive coupling of light from a ridge waveguide to a photonic crystal waveguide. We demonstrate an average improvement of 62% in coupling to low group velocity modes and an average coupling enhancement of 11.5% at large group velocities.

Quality Factor Enhancement of Optical Channel Drop Filters Based on Photonic Crystal Ring Resonators
In this paper, a channel drop ring resonator filter based on two dimensional photonic crystal is proposed which is suitable for all optical communication systems. The multilayer of silicon rods in the center of resonant ring enables one to adjust resonant wavelength of the ring and enhance power coupling efficiency between ring and waveguide. Refractive index and radius of multilayer rods insid...
متن کاملBroadband optical coupling between microstructured fibers and photonic band gap circuits: Two-dimensional paradigms
We demonstrate high efficiency, broadband coupling between photonic crystal waveguides and photonic crystal fibers PCFs using simple two-dimensional design models. We demonstrate an effective largebandwidth small-footprint beam collimator for light exiting a two-dimensional subwavelength scale photonic crystal waveguide consisting of an air core. This collimator relies on destructive interferen...
متن کاملCoupling into the slow light mode in slab-type photonic crystal waveguides.
Coupling external light signals into a photonic crystal (PhC) waveguide becomes increasingly inefficient as the group velocity of the waveguiding mode slows down. We have systematically studied the efficiency of coupling in the slow light regime for samples with different truncations of the photonic lattice at the coupling interface between a strip waveguide and a PhC waveguide. An inverse powe...

A photonic crystal-based TE to TM polarization converter for integrated optical communication is proposed in this paper. The photonic crystal consists of air circular-holes in slab waveguide. The radius of holes are determined to be 291nm having lattice constant of 640nm using the gap map and band diagram. The polarization converter is composed of an InGaAsP triangular-shaped waveguide on SiO2 ...
متن کاملAdd-Drop and Channel-Drop Optical Filters Based on Photonic Crystal Ring Resonators
Here, we propose an add-drop and a channel drop filter based on two-dimensional photonic crystal all circular ring resonators. These structures are made of a square lattice of silicon rods with the refractive index n1=3.464 surrounded by air (with refractive index n2=1). The broadest photonic band gap occurs at the filling ratio of r/a = 0.17. Two linear defect W1 waveguides couple to the ring....
