Two dimensional tunable photonic crystal defect based drop filter at communication wavelength
2017, Photonics and Nanostructures - Fundamentals and ApplicationsCitation Excerpt :The different photonic crystal based filters like add-drop filters [5], channel drop filters [6,7], band pass and stop filters [8–11], etc., have been proposed and realized experimentally. The channel drop filters are essential part of the photonic communication systems and optical integrated chips [12]. They selectively transmit, one wavelength among a set of wavelengths of wavelength division multiple optical signal, and considered as a suitable candidate for the channel drop in wavelength division multiplexing systems.
Photonic crystal channel drop filter based on ring-shaped defects for DWDM systems
2017, Physica E: Low-Dimensional Systems and NanostructuresExternal tunability of optical filter in symmetric one-dimensional photonic crystals containing ferroelectric and ITO material defect
2016, OptikCitation Excerpt :These defect modes mainly result from the change of the interference approach of light, and such defective photonic structures are often useful in the design of narrow band transmission filters [9,10] . A tunable defect mode can be utilized to design and fabricate the PCs for various applications in optoelectronic and microwave devices such as optical modulators, tunable resonators, switches and sensing devices [11–13]. Changing the physical or optical parameters (thickness, permittivity or number of periodicity) of the defect layer would lead to shift in the peak frequency of the defect mode or PBG.
Photonic crystal wedge as a tunable multichannel filter
2015, Superlattices and MicrostructuresWavelength-division-multiplexing system with photonic crystal self-collimation and co-directional coupling effect
2014, OptikCitation Excerpt :This is because of the weak coupling in horizontally arranged couplers. Recently, different photonic crystal WDM systems based on channel drop filters have been proposed [13–21]. Among various PC wavelength selective filters, add–drop filters utilizing resonant coupling between microcavity modes produced by point defects and waveguide modes created by line defects have recently become the focus of much attention [18–21].
Multi-channel drop filters using photonic crystal ring resonators
2012, OptikCitation Excerpt :Optical waveguides in two-dimensional (2D) PCs produced by insertion of linear defects into PC structures had been proposed [4]. Planar PC circuits consist of devices, such as splitters [5], Wavelength Division Demultiplexers, filters [6], and channel drop filters [7], by controlling the interaction between static devices, such as waveguides, resonators. A multi-channel drop filter consists of two parts, a waveguiding element, realized by linear defects in a photonic crystal, and frequency-selective elements, realized by photonic crystal resonators.
