“…The inset in the Fig. 2a shows the normalized transmission loss for different waveguide length and the transmission loss was found to be 1dB/cm, comparable to that reported in [6]. The use of polymers such as the ORMOCER series can further reduce the transmission loss, due to their intrinsic low material loss, as highlighted in [7].…”

Abstract-We have performed an exploration of inverted rib waveguide platform for use in optical backplanes. This entailed the design, optimization, and characterization of a variety of passive optical components that may serve as a basis for the functions required of an on-chip optical networks. The presented design introduces an inverted-rib template which consists of a polymer waveguide layer. We have successfully fabricated and demonstrated low-loss waveguides, and also functional passive devices such as directional couplers, multi-mode interferometers, waveguide bends and crossings, and distributed Bragg reflectors. We also demonstrate a way of coupling active components (e.g. in silicon) to such a photonic integrated circuit.Index Terms-Optical backplane, opto-electronic integration, polymer waveguide, passive optical components.

“…We readily see that the loss coefficient significantly increases as the specified FSR becomes larger. Given that the scattering-induced loss in straight SU8 ridge waveguides is ≅1 dB/cm [17], we understand from Fig. 4(b), that for FSR larger than 0.6 THz, bending loss can become the most significant loss contribution.…”

“…The propagation loss of SU-8 dielectric waveguide was previously reported as 1 dB/cm at 1550 nm. 31 Since most parts of the evanescent tails of the LRSPP mode lie in the cladding region, SU-8 is chosen as the low-loss dielectric claddings in this work. Gold has been chosen as a superior material in plasmonic devices due to its inert chemical reaction and a large negative dielectric constant in real part at visible to near-infrared wavelengths, which yields high plasmonic efficiencies at this region.…”

Long-range surface plasmon polariton waveguides composed with thin gold stripes embedded in SU-8 polymer cladding with various stripe widths were fabricated. Material properties of the polymer cladding layer, gold thin film, and the device structures were discussed. Optical properties based on modal propagation were characterized at visible to near-infrared wavelengths. The measured propagation losses of waveguide widths from 3 to 9 μm at 633, 785, and 1550 nm are 7.5-18.8, 6.8-12.5, and 1.9-3.9 dB/mm, respectively. Guiding mode properties such as overlap integrals between the simulated and the measured fields and the polarization extinction ratios of the waveguides with different stripe widths were investigated at the telecommunication wavelength. Good accordance between the measurement and simulation results was presented.
