The optical system used a standard fiber coupler Michelson interferometer topology (Fig. 1 ), and the sample arm optics delivered a spot size at the cornea and the retina of 1.3mm and 17μm (assuming a 25mm axial eye length), respectively.
The main building block for all channels is a symmetric combination of standard fiber couplers (AC-Photonics) for spectrally flat response [ 31].
Originally fitted with a standard link and pin type coupler, 381 was later fitted with a Tomlinson automatic style coupler (although it was not able to operate in multiple with the H type). Power operated doors were also fitted.
When coupled with a weakly guided buried channel silica waveguide, a very narrow bandwidth filter (<1 nm) can be easily produced, in a shorter length, with respect to directional couplers made with standard step index channel waveguides.
Partial discharge measurements were taken simultaneously with piezoelectric sensors and with a standard detection circuit equipped with a capacitive coupler.
Magnetic coupler selection, battery selection and different safety standards for WPT design are mentioned in this paper.
The device consists of a dielectric-loaded decelerating structure and two changeable output couplers to deliver the millimeter-wave power to a standard waveguide.
A standard fiber-based OCT instrument is operated in Michelson interferometer configuration, connecting the fiber coupler (OZ Optics, Ontario, Canada) with 90/10 splitting ratio.
Laser cavity mirrors had standard λ/4 dielectric coatings centered near 1064 nm (CASIX, Inc., Fuzhou, China, www.casix.com); the output coupler (EKSPLA) had 5% transmissivity at 1030 nm.
By combining four exponential-tapered MMI couplers, a novel compact 0.6 cm-long triplexer that is with ITU standard wavelength of 1310 nm, 1490 nm and 1550 nm for FTTH is achieved without requiring complicated design.
