We present the integrated chip-scale tuning of multiple photonic crystal cavities. The optimized implementation allows for large tuning (20K/mW), with deterministic resonance control towards all-optical analogue to electromagnetically-induced-transparency on-chip.

Deterministic integrated tuning of multicavity resonances and phase for slow-light in coupled photonic crystal cavities
Gu, T.; Kocaman, Serdar; Yang, X.; McMillan, J.F.; Yu, M.B.; Lo, G.-Q.; Kwong, D.-L.; Wong, C.W. (AIP Publishing, 2011-03-21)
We present the integrated chip-scale tuning of multiple photonic crystal cavities. The optimized implementation allows effective and precise tuning of multiple cavity resonances (up to similar to 1.60 nm/mW) and intercavity phase (similar to 0.038 pi/mW) by direct local temperature tuning on suspended silicon nanomembranes. Through designing the serpentine metal electrodes and careful electron-beam alignment to avoid cavity mode overlap, the coupled photonic crystal L3 cavities preserve their high quality f...
Micro fluxgate sensor with cascaded planar ring cores
Zorlu, O.; Kejik, P.; Teppan, W. (2009-09-09)
In this paper, we present a new microfabricated fluxgate sensor structure having cascaded planar rings as the ferromagnetic core. A circular magnetic excitation is provided with a rod passing through the FeNi rings as a sewing thread. Planar coils placed under the edges of the core are used as sensing elements. The sensing coils and the excitation rod are made of AlSi, and the planar FeNi ferromagnetic core is electroplated in between the excitation rod metallization. The sensor with 18 cascaded cores has 6...
Tuning of 2D Rod-Type Photonic Crystal Cavity for Optical Modulation and Impact Sensing
Orsel, Ogulcan E.; Erdil, Mertcan; Yanik, Cenk; Kocaman, Serdar (2019-01-01)
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 m...
Bulk PZT Cantilever Based MEMS Acoustic Transducer for Cochlear Implant Applications
Koyuncuoğlu, Aziz; İlik, Bedirhan; Chamanian, Salar; Uluşan, Hasan; Ashrafi, Parinaz; Işık, Dilek; Külah, Haluk (2017-08-11)
This paper presents the first acoustic experimental results of a MEMS based bulk piezoelectric transducer for use in fully implantable cochlear implants (FICI). For this purpose, the transducer was attached onto an acoustically vibrating membrane. Sensing and energy harvesting performances were measured using neural stimulation and rectifier circuits, respectively. The chip has a 150 Hz bandwidth around 1800 Hz resonance frequency that is suitable for mechanical filtering as a sensor. As an energy harvester...
Local thermal resonance control of GaInP photonic crystal membrane cavities using ambient gas cooling
Sokolov, Sergei; LİAN, Jin; Yüce, Emre; COMBRİÉ, Sylvain; LEHOUCQ, Gaelle; De Rossi, Alfredo; Mosk, Allard P. (2015-04-27)
We perform spatially dependent tuning of a GaInP photonic crystal cavity using a continuous wave violet laser. Local tuning is obtained by laser heating of the photonic crystal membrane. The cavity resonance shift is measured for different pump positions and for two ambient gases: He and N-2. We find that the width of the temperature profile induced in the membrane depends strongly on the thermal conductivity of the ambient gas. For He gas, a narrow spatial width of the temperature profile of 2.8 mu m is pr...
