Fabry-Perot interferometer is an optical resonator consisting of two parallel mirrors. Fabry-Perot interferometers can be made by silicon bulk microma-chining." " Silicon surface micromachining is also a suitable technique for making interferometers for infrared wavelengths. 

Since the separation energies between these sharp features in the 1D DOS are strongly dependent on the CNT diameter, a change in the laser excitation energy may bring into optical resonance a CNT with a different diameter. However,... 

All lasers have the following three fundamental components (see Figure 1). The gain medium, the business end of the laser, is the medium in which excited states are created which will produce stimulated emission. The exciter is the source of energy for production of the excited states in the gain medium. Finally, the optical resonator determines the directionality, wavelength selectivity, optical feedback, polarization, and other characteristics of the stimulated emission from the gain medium.

We anticipate that, regardless of the detuning from an optical resonance used, the parameters f, g, and h will always be determinable from measurements of SHG as a function of the rotation angle of a quarter waveplate used to set the polarization state of the incident fundamental light. The amount of SHG-CD can be calculated from the parameters or, of course, read directly... 

The collection of chapters in this book represents the most recent global efforts in the research and development of photonic bio/chemical sensing structures. The photonic structures included in book are quite diversified, ranging from optical resonators and interferometers to photonic crystals and specially designed waveguides. For guidance, they are summarized as follows ...

The principle of an MNF performance as an optical sensor is based on the variation of the MNF transmission spectrum in response to changes in the ambient medium. More advanced photonic sensors exploiting MNFs allow to enhance these variations and/or to make them more selective. This section briefly reviews the basic theory of simplest resonant photonic sensors. In these devices, an MNF either form an optical resonator or serve as an input and output connection to an optical resonator. These devices include the MLR23-26, the MCR8,26-33, the MNF/micro-sphere resonator34-45, the MNF/microdisk resonators46-49, and the MNF/microcy-linder resonator18,50-54.

To use the OFRR as a biosensing device, the optical resonant mode is excited and the resonant frequency is measured continuously in real time. The conceptual measurement setup is illustrated in Fig. 14.3. Laser light from a distributed feedback (DFB) laser is delivered to the OFRR using fiber optic cable. One method that has been used to excite the resonant modes is to place a tapered fiber optic cable with a diameter less than 4 pm in contact with the OFRR. The evanescent field of the tapered fiber overlaps with the evanescent field outside of the capillary wall, which enables mode coupling between the two media24. 

Optically Resonant Nanophotonic Devices for Label-Free Biomolecular Detection... 

The goal of this chapter will be to provide an overview of the use of planar, optically resonant nanophotonic devices for biomolecular detection. Nanophotonics23 24 represents the fusion of nanotechnology with optics and thus it is proposed that sensors based on this technology can combine the advantages of each as discussed above. Although many of the issues are the same, we focus here on optical resonance rather than plasmonic resonance (such as is used in emerging local SPR and surface-enhanced Raman spectroscopy-based biosensors).
