Deterministic design of wavelength scale, ultra-high Q photonic crystal nanobeam cavities.
Photonic crystal nanobeam cavities are versatile platforms of interest for optical communications, optomechanics, optofluidics, cavity QED, etc. In a previous work [Appl. Phys. Lett. 96, 203102 (2010)], we proposed a deterministic method to achieve ultrahigh Q cavities. This follow-up work provides systematic analysis and verifications of the deterministic design recipe and further extends the ...
متن کاملHigh Quality factor photonic crystal nanobeam cavities
We investigate the design, fabrication and experimental characterization of high Quality factor photonic crystal nanobeam cavities in silicon. Using a five-hole tapered 1D photonic crystal mirror and precise control of the cavity length, we designed cavities with theoretical Quality factors as high as 1.4 × 10. By detecting the cross-polarized resonantly scattered light from a normally incident...
متن کاملProgrammable photonic crystal nanobeam cavities.
We present dynamically reconfigurable photonic crystal nanobeam cavities, operating at ~1550 nm, that can be continuously and reversibly tuned over a 9.5 nm wavelength range. The devices are formed by two coupled nanobeam cavities, and the tuning is achieved by varying the lateral gap between the nanobeams. An electrostatic force, obtained by applying bias voltages directly to the nanobeams, is...
متن کاملDynamically Reconfigurable Photonic Crystal Nanobeam Cavities
Wavelength-scale, high Q-factor photonic crystal cavities [1, 2] have emerged as a platform of choice for on-chip manipulation of optical signals, with applications ranging from low-power optical signal processing [3] and cavity quantum electrodynamics [4, 5] to biochemical sensing. Many of these applications, however, are limited by the fabrication tolerances and the inability to precisely con...
متن کاملMomentum space design of high-Q photonic crystal optical cavities.
The design of high quality factor (Q) optical cavities in two dimensional photonic crystal (PC) slab waveguides based upon a momentum space picture is presented. The results of a symmetry analysis of defect modes in hexagonal and square host photonic lattices are used to determine cavity geometries that produce modes which by their very symmetry reduce the vertical radiation loss from the PC sl...
