An area efficient novel optical modulator with low operation voltage is designed based on integrated Mach-Zehnder Interferometer with a photonic crystal slab structure as the phase shifter. Plasma dispersion effect is utilized so that photonic band-to-band transition occurs at the operating frequency leading to a high index change (Delta n = similar to 4) for pi-phase shift on the modulator. This approach reduces the phase shifter length to a few micrometers (similar to 5 mu m) in a silicon on insulator platform and operating voltage required is around 1 V. Low voltage together with short optical interaction length decrease optical losses and power consumption during modulation process providing a great opportunity for size and system cost optimization.

Integrated optical modulators with zero index metamaterials based on photonic crystal slab waveguides Yildirim, Mustafa; GÖVDELİ, ALPEREN; Kocaman, Serdar (2019-01-01) A novel integrated optical modulator design is presented using zero index metamaterial-based Mach-Zehnder Interferometer with photonic crystal phase shifters. The phase modulation relies on the shift between the photonic bandgaps having non-zero and zero effective refractive indices. A small change in the bulk index results in an effective index change between the arms of the MZI due to the disturbance of the band structure. Thus, such a structure provides a new approach for phase modulation on integrated o...
Band-to-Band Transition Based On-Chip Optical Modulator Gövdeli, Alperen; Sarihan, Murat Can; Karaca, Utku; Kocaman, Serdar (2018-10-04) Photonic crystal slab phase shifter based, area efficient and low operation voltage optical modulator design is presented. Required index difference between the Mach-Zehnder interferometer arms of the proposed modulator comes from the photonic band transition.
Design optimization of a fully integrated charge-pump with LC tank oscillator for ultra-low voltage energy harvesting Jayaweera, H. M. P. C.; Muhtaroglu, Ali (2017-01-01) Model based optimization of a novel integrated interface circuit topology is presented for low voltage DC-DC step-up conversion. A cross-coupled charge pump is implemented in standard 0.18 mu m CMOS technology using an integrated LC tank oscillator to enable a compact, low cost, self-starting solution with maximum efficiency at ultra-low input voltage levels available from embedded micro-power generators. The voltage doubling oscillator can start up with input as low as 0.10 V. Full system can step 0.2 V up...
Frequency tunable microstrip patch antenna using RF MEMS technology Erdıl, Emre; Topallı, Kagan; Unlu, Mehmet; Aydın Çivi, Hatice Özlem; Akın, Tayfun (2007-04-01) A novel reconfigurable microstrip patch antenna is presented that is monolithically integrated with RF microelectromechanical systems (MEMS) capacitors for tuning the resonant frequency. Reconfigurability of the operating frequency of the microstrip patch antenna is achieved by loading it with a coplanar waveguide (CPW) stub on which variable MEMS capacitors are placed periodically. MEMS capacitors are implemented with surface micromachining technology, where a 1-mu m thick aluminum structural layer is plac...
Highly efficient and broadband light transmission in 90 degrees nanophotonic wire waveguide bends KURT, HAMZA; Giden, I. H.; Ustun, K. (The Optical Society, 2011-03-01) Nanophotonic wire silicon waveguides are indispensable components of integrated photonic circuits. Because of the inherent nature of these waveguides, such as narrow width and high-index contrast, corners with large bending radii are inevitable for efficient light transmission with small loss values, which, in turn, impedes the miniaturization of photonic components. To alleviate huge bending losses of a right angle waveguide, we designed a structure incorporating a two-dimensional (2D) photonic crystal, al...
