“…Here, the spot size is defined as the FWHM of the guided mode profile, and the CD is defined as twice the size of the pitch between air holes. Unlike the SMF cases [5][6][7][8], the relation between the spot size and the CD of a PCF is quite linear until the core diameter becomes close to the wavelength of guided light. However, it is observed that the spot size becomes a little bit larger than the CD when the CD becomes compatible to the wavelength of the guided mode (1552 nm).…”

“…The tapered optical fibers are primarily used in order to use the efficient coupling of light from an optical fiber into many integrated optical devices, e.g., laser diodes, arrayed waved guide gratings, modulators, or semiconductor optical amplifiers. However, the tapered single-mode fiber (SMF) has some problems in coupling light directly into a waveguide [6]. A tapered SMF restricts its single-mode guiding properties to a limited wavelength region [7].…”

We have fabricated tapered photonic crystal fibers using a fusion splicer and experimentally observed the near-field mode distribution and the beam divergence of it. We have also compared characteristics of the tapered photonic crystal fiber with those of a tapered standard single-mode fiber. Unlike a tapered standard single-mode fiber, the mode field profile of a tapered photonic crystal fiber shows a good confinement of its field within the core region. The numerical apertures of tapered photonic crystal fibers are increased as the diameter of the fiber is decreased.

“…Coupling to and from these devices usually involves high losses resulting from mode-size and effective-index mismatch between the optical fiber and the waveguide structure, which induces coupling to radiation modes and back reflection. To date, most of the on-chip structures suggested to alleviate this coupling problem [48][49][50][51] have suffered from at least one of the following drawbacks: they are very long (hundreds of micrometers), are difficult to fabricate or have strong backreflection. Therefore tapered devices that transition from waveguide dimensions to the fiber dimensions have been suggested.…”

Chip-scale optomechanical resonators have the advantage of higher Q values, smaller dimensions, and thus a greater potential for scalability and device control. This chapter discusses further integration of chip-scale optomechanic elements on a circuit level. Circuit integrated optomechanics brings a range of additional benefits for both fundamental studies and practical device applications of optomechanics. It takes advantage of many circuit components that have been developed by the nanophotonics community, such as grating couplers, splitters, combiners and low loss waveguides, which can be directly utilized to form scalable circuits for routing optical signals. High quality photonic resonators and band-gap structures, such as microring, microdisk, and photonic crystal nanocavities, can be seamlessly embedded in the circuit for direct interfacing with nanomechanical resonators without suffering from significant optical loss. Homodyne detectors, such as Mach-Zehnder interferometers, are implemented directly as part of the circuit to achieve sensitive, alignment free measurement of mechanical motion. Circuit optomechanics not only leads to further scaling of optomechanical systems but also brings new interaction dynamics in light-mechanics coupling. We will discuss the various radiation dynamics and non-radiation dynamics that are present in circuit optomechanical systems. Integrated Optomechanics and Optomechanical CircuitsLately we have witnessed rapid progress in cavity optomechanics with demonstration of dynamic back-action cooling and amplification of mechanical structures of vastly different length scales. In particular, chip-scale optomechanical resonators

“…When the bias current was modulated, the optical beam power and optical wavelength became modulated as well. The optical beam is coupled to the tapered fiber (Shani et al, 1989;Alder et al, 2000), which is connected to a Mach-Zehnder fiber interferometer (Saunders et al, 1994;Jeong & Park, 1997;Laverdiere et al, 2003). An optical amplifier can be used if the interferometer output signal is too weak.…”
