Compact wavelength de-multiplexer design using slow light regime of photonic crystal waveguides

Akosman, A.E.; Mutlu, M.; Kurt H.; Özbay, Ekmel (Optical Society of American (OSA), 2011)

We demonstrate the operation of a compact wavelength demultiplexer using cascaded single-mode photonic crystal waveguides utilizing the slow light regime. By altering the dielectric filling factors of each waveguide segment, ...
Dual-frequency division de-multiplexer based on cascaded photonic crystal waveguides

Akosman, Ahmet E.; Mutlu, Mehmet; Kurt, H.; Özbay, Ekmel (Elsevier, 2012-02-28)

A dual-frequency division de-multiplexing mechanism is demonstrated using cascaded photonic crystal waveguides with unequal waveguide widths. The de-multiplexing mechanism is based on the frequency shift of the waveguide ...
Physics and applications of defect structures in photonic crystals

Özbay, Ekmel; Bayındır, Mehmet (Springer, 2003)

We propose and demonstrate a new type of propagation mechanism for electromagnetic waves in photonic band gap materials. Photons propagate through coupled cavities due to interaction between the highly localized neighboring ...
