Programmable 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 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 کاملSuspended GaN-based band-edge type photonic crystal nanobeam cavities.
We demonstrated GaN-based photonic crystal (PC) nanobeam cavities by using the e-beam lithography and the suspended nanobeams were realized by focused-ion beam (FIB) milling. One resonant mode was clearly observed at 411.7 nm at 77K by optical pumping. The quality factor was measured to be to 7.4 × 10(2). Moreover, the degree of polarization value was measured to be 40%. The temperature-depende...
متن کاملCharacterization of 1D photonic crystal nanobeam cavities using curved microfiber.
We investigate high-Q, small mode volume photonic crystal nanobeam cavities using a curved, tapered optical microfiber loop. The strength of the coupling between the cavity and the microfiber loop is shown to depend on the contact position on the nanobeam, angle between the nanobeam and the microfiber, and polarization of the light in the fiber. The results are compared to a resonant scattering...
