Fiber-to-chip light coupling using a graded-index lensed fiber collimator
نویسندگان
چکیده
Fiber-to-chip light coupling using a graded-index (GRIN) fiber collimator is investigated. Our experiments with grating couplers and strip waveguides fabricated in photonic integrated circuit technology reveal that the peak efficiency of GRIN 7.8 dB lower than single-mode fiber. However, 3-dB alignment tolerance improved by factor about 5.7 giving rise to pluggable sensor solutions. This work opens path toward cost-effective portable platform based on biosensors collimators.

Optical coupling method utilizing a lensed fiber integrated with a long-period fiber grating.
A novel optical coupling scheme that uses a lensed fiber integrated with a long-period fiber grating (LPFG) is proposed. Two experiments are performed to demonstrate the validity of such a scheme in single-mode-fiber-single-mode-fiber (SMF-to-SMF) and laser-diode-single-mode-fiber (LD-to-SMF) coupling setups. The measured results show that for an appropriate lens radius the addition of a LPFG w...

Plastic Optical Fiber Perfluorinated graded-index polymer optical fibers (GI-POFs) combine high data transmission rates and low attenuation in the commercially desirable 850–1300nm range. GI-POFs offer a direct replacement and a low cost alternative to traditional glass. With ease of use and affordability, GI-POFs make an excellent choice for the installation of high performance fiber networks....
متن کاملMEMS compatible micro-GRIN lenses for fiber to chip coupling of light.
Graded-Index (GRIN) lenses with a diameter of 125 mum are presented. This diameter enables the assembly of the GRIN lenses onto an optical micro-system using the same passive alignment grooves as used for the light carrying optical fibers. In contrast to refractive lenses, GRIN lenses have flat endfaces and the focal distance of a GRIN lens is defined by its length. Therefore, GRIN lenses can b...
متن کاملGraded-index polymer optical fiber for high-speed data communication.
We successfully obtained a high-bandwidth (1 GHz km) and low-loss (90 dB/km at 0.572 µm of wavelength) graded-index polymer optical fiber by using the interfacial-gel polymerization technique, in which we used an unreactive component to obtain the quadratic refractive-index distribution. This high-bandwidth graded-index polymer optical fiber makes it possible to transmit a high-speed optical si...
متن کاملNear-infrared multispectral photoacoustic microscopy using a graded-index fiber amplifier
We demonstrate optical resolution photoacoustic microscopy (OR-PAM) of lipid-rich tissue using a multi-wavelength pulsed laser based on nonlinear fiber optics. 1047 nm laser pulses are converted to 1098, 1153, 1215, and 1270 nm pulses via stimulated Raman scattering in a graded-index multimode fiber. Multispectral PAM of a lipid phantom is demonstrated with our low-cost and simple technique.
