We propose a novel way of mechanical perturbation of photonic crystal cavities for on-chip applications. We utilize the equivalence of the 2D photonic crystals with perfect electric conductor (PEC) boundary conditions to the infinite height 3D counterparts for rod type photonic crystals. Designed structures are sandwiched with PEC boundaries above and below and the perturbation of the cavity structures is demonstrated by changing the height of PEC boundary. Once a defect filled with air is introduced, the metallic boundary conditions is disturbed and the effective mode permittivity changes leading to a tuned optical properties of the structures. Devices utilizing this perturbation are designed for telecom wavelengths and PEC boundaries are replaced by gold plates during implementation. For 10 nm gold plate displacement, two different cavity structures showed a 21.5 nm and 26 nm shift in the resonant wavelength. Optical modulation with a 1.3 MHz maximum modulation frequency with a maximum power consumption of 36.81 nW and impact sensing with 20 µs response time (much faster compared to the commercially available ones) are shown to be possible.

Erbium doped silicon photonic crystals for light sources and amplifiers Vuckovic, Jelena; Makarova, Maria; Gong, Yiyang; Yerci, Selçuk; Li, Rui; Negro, Luca Dal (null; 2009-01-01) We demonstrated enhancement of light emission from Er-doped silicon photonic crystal cavities, as well as cavity linewidth narrowing with increasing optical pump power at low temperature-an indication of differential gain in the system.
Flexible waveguides with amorphous photonic materials Sarihan, Murat Can; Yilmaz, Yildirim Batuhan; Erdil, Mertcan; Aras, Mehmet Sirin; Yanik, Cenk; Wong, Chee Wei; Kocaman, Serdar (2019-01-01) Amorphous photonic materials offer an alternative to photonic crystals as a building block for photonic integrated circuits due to their shared short-range order. By using the inherent disorder of amorphous photonic materials, it is possible to design flexible-shaped waveguides that are free from restrictions of photonic crystals at various symmetry axes. Effects of disorder on photonic crystal waveguide boundaries have examined before, and it is shown that flexible waveguides with high transmission are pos...
Analysis of photonic-crystal problems with MLFMA and approximate Schur preconditioners Ergül, Özgür Salih; Kilinç, Seçil; Sarıtaş, Serkan (2009-07-23) We consider fast and accurate solutions of electromagnetics problems involving three-dimensional photonic crystals (PhCs). Problems are formulated with the combined tangential formulation (CTF) and the electric and magnetic current combined-field integral equation (JMCFIE) discretized with the Rao-Wilton-Glisson functions. Matrix equations are solved iteratively by the multilevel fast multipole algorithm. Since PhC problems are difficult to solve iteratively, robust preconditioning techniques are required t...
Optimization of metalization in crystalline silicon solar cells Demircioğlu, Olgu; Turan, Raşit; Ünalan, Hüsnü Emrah; Department of Micro and Nanotechnology (2012) Production steps of crystalline silicon solar cells include several physical and chemical processes like etching, doping, annealing, nitride coating, metallization and firing of the metal contacts. Among these processes, the metallization plays a crucial role in the energy conversion performance of the cell. The quality of the metal layers used on the back and the front surface of the cell and the quality of the electrical contact they form with the underlying substrate have a detrimental effect on the amou...
Development of CuNiSi-x alloy catenary parts by thermomechanical processing for railway applications Koç, Ömer Faruk; Kalkanlı, Ali; Department of Metallurgical and Materials Engineering (2017) Electrical conductivity together with some other mechanical properties like strength is needed for catenary systems in railway applications. In recent years, copper and its alloys especially the ones with Ni and Si which can mostly satisfy these mechanical needs are extensively researched. For this reason, uses of CuNiSi base alloys have become widespread. In the research study CuNiSi base alloys were put through several treatments to improve their properties. These treatments were basically melting and cas...
