“…, the large index change (Δn % 0.05) of the liquid crystal enabled the wide spectral tuning, through electrical [35] and thermal [36] effects. Recently, the integration with microfluidics and the perturbation with a tapered fiber and a fiber tip on photonic crystal structures have also been reported [29,33,[37][38][39][40][41][42]. Comparison with various post trimming techniques for the fabricated cavity was summarized extensively in the previous LPR article by Grillet et al.…”

Recent progress in the field of re-locatable photonic crystal resonators is discussed with a particular emphasis on the flexible scheme that employs highly-curved microfiber. In this scheme a spectrally-tunable high-quality-factor resonator can be defined repeatedly by physically moving a curved microfiber to a new position. When a curved microfiber is placed on top of a photonic crystal waveguide (or photonic crystal), a photonic well is newly created in the vicinity of the contact point. Inside of this photonic well, high-quality-factor resonant modes are generated at frequencies below the cutoff edge of the guided mode. The tapered microfiber is an integral part of a single mode optical fiber and efficient out-coupling is naturally obtained. The sub-nanometer spectral tuning capability that is available by changing the curvature of the microfiber is also an important characteristic and discussed. This spectrally-and spatiallyreconfigurable photonic crystal resonator is expected to be a potential platform for photonic crystal based single photon sources, which enables accurate spatial overlap and spectral overlap with a single quantum dot, together with straightforward photon out-coupling to the fiber with high efficiency.

“…Within this framework, the possibility to control the spectrum of a PhCC has been an active field of research in the last decade. The problem of the tuning of photonic modes has been addressed not only from a fundamental point of view, but also through cavity engineering [10] and through the development of post-fabrication techniques [11][12][13][14][15], quite often born in order to compensate fabrication induced disorder. Large mode tuning with minor reduction of quality factor Q has been recently demonstrated by the electromechanical control of the distance between two PhCCs realized on two closely spaced parallel membranes [16][17][18].…”

We propose a force sensor, with optical detection, based on a reconfigurable multicavity photonic molecule distributed over two parallel photonic crystal membranes. The system spectral behaviour is described with an analytical model based on coupled mode theory and validated by finite difference time domain simulations. The deformation of the upper photonic crystal membrane, due to a localized vertical force, is monitored by the relative spectral positions of the photonic molecule resonances. The proposed system can act both as force sensor, with pico-newton sensitivity, able to identify the position where the force is applied, and as torque sensor able to measure the torsion of the membrane along two perpendicular directions.

“…A near-field optical microscope (NSOM) can be used to achieve this effect. Indeed it has been shown that a NSOM probe can be used to alter the modal properties of passive nanophotonic structures [15][16][17][18][19][20][21][22]. These studies hinted that if the electromagnetic coupling between a near-field probe and a photonic mode can be controlled, this could open new avenues for the design of novel optomechanic photonic devices.…”

Abstract:The influence of a near-field tip on the spectral characteristics of a resonant mode of an active photonic crystal micro-cavity was investigated. The wavelength shift of the mode was theoretically and experimentally demonstrated and evaluated as a function of the nature and the position of the tip above the cavity. Experiment showed that the shift induced is ten times higher with a Si-coated silica probe than with a bare silica tip: a shift until 2 nm was reached with Si-coated tip whereas the shift with bare silica tip is in the range of the tenth of nanometer, for wavelengths around 1,55 µm. ©2009 Optical Society of America
