“…In fact, the diameter of the core of singlemode fibers is around 10 m for m and around 4 m for m. Other approaches to replace the array of microlenses have been reported. The fabrication of a lens directly on top of the fiber as was proposed for laser to fiber coupling by [15] and [16] (arc discharge machining), and by [17] and [18] (laser micromachining). Nevertheless, the surface of such microlenses is difficult to fabricate accurately.…”

Abstract-The authors investigate a 1 free-space microoptical fiber switch for a large number of interconnects. The system to be studied is a reflective 4 optical system. Alignment tolerances and coupling efficiency are investigated and the benefit brought by collimating microlens arrays is reported (theoretically and experimentally). The use of microlenses enables power coupling efficiency between 3 and 2 dB (including losses due to the optical elements) for an optical switch allowing up to 3000 receiver fibers.

“…A lens is needed to collect the diverging beam coming out of the end of the fiber. A micro lens fabricated at the end of the fiber can replace traditional bulk optical components and has the advantage of self-alignment with the fiber [7,8]. A hemispherical micro lens with a large radius R and long working length compared to other works was designed and fabricated [9].…”

As the recording density of longitudinal magnetic storage increases at a 100% annual growth rate, it will soon approach the superparamagnetic limit where the thermal energy at room temperature starts to induce thermal instability to the grains in the small recorded marks. Thermal magnetic recording schemes, such as those used in magneto-optical recording, help alleviate the problems with the superparamagnetic limit. Recently, a hybrid recording system was proposed where data were recorded thermal magnetically on a magneto-optical disk and read back with a GMR head. In this paper, we propose an integrated planar head that combines an optical fiber lens, a solid immersion lens, a sub wavelength aperture, a micro coil, an air bearing surface, and a GMR head for such a hybrid recording system. Preliminary fabrication and calculation are discussed.

“…Such components are used in a myriad of applications, such as in lab-on-a-chip systems [1,2], enhancement of LEDs out-coupling efficiency [3,4], fluorescence sensors [5], fibre coupling [6], scanning [7] or imaging [8]. Several approaches have been proposed in order to obtain the microlenses.…”

a b s t r a c tA system of two solid microlenses with uncoupled optical properties is presented. This structure has been designed in order to have one lens as a reference, while the other one can be mechanically tuneable. The reference lens presents a diameter of 2 m and it is placed in the optical axis of the mechanically tuneable lens, which has a diameter of 10 m. The proposed microoptical structure has been fabricated in poly(dimethilsiloxane) (PDMS) merging deep reactive ion etching, SU-8 and soft lithography, with a low-cost (mass-production), simple and highly repetitive technology. This device was numerically simulated prior to its fabrication, to optimize its design and improve its behaviour. In addition, an optical characterization of the fabricated devices was carried out. Both simulation and experimental results shows a good agreement, under mechanical actuation behaviour of the reference lens is invariable, while the tuneable lens become an elliptic lens and the interval of Sturm can be observed. These results provide a proof of concept of the proposed devices and validate both the design and the fabrication technology.
