“…The 1) and the fabricated SM waveguide at 1310-and 1550-nm wavelengths are measured by an optical beam NFP measurement optics (SYNERGY OPTOSYSTEMS CO., LTD., M-Scope type S), as shown in Fig. 8 [12]. In addition, the normalized output intensity profiles obtained from the NFPs of fabricated SM waveguides at both wavelengths are also shown in Fig.…”

“…In this paper, we demonstrate that the Mosquito method is very promising for fabricating even SM polymer waveguides because the core diameter is controlled accurately and easily. Although we already reported the possibility of SM waveguide fabrication using the Mosquito method in [11,12], the optical loss and other characteristics of the fabricated SM waveguide have not been fully investigated.…”

We fabricate low-loss single-mode (SM) polymer optical waveguides using a photomask-free simple technique named the Mosquito method. The insertion losses of a 5-cm long SM polymer waveguide fabricated are 2.52 dB and 4.03 dB at 1310- and 1550-nm wavelengths, respectively. The coupling loss between a single-mode fiber and the waveguide is as low as 0.5 dB including the Fresnel reflection. The 0.5-dB misalignment tolerance in the radial direction is ± 2.0 μm at 1550 nm. The Mosquito method is promising for fabricating SM polymer optical waveguides compatible with silicon photonics chips.

“…Major requirements for on-chip optical signal transmission and processing are low propagation losses and polarization dependent losses (PDL) [2,5]. Several groups successfully developed polymer buried channel waveguides [6][7][8] and chalcogenide glass rib waveguides [9] which fulfill aforementioned requirements. However, these platforms suffer from low core-cladding refractive index contrast and specific rib waveguide geometry, respectively.…”

-Integrated polymer photonics brings low cost and high fabrication flexibility to optoelectronic industry. However, this platform needs to overcome several issues to be efficient enough for practical applications. In this work, we experimentally demonstrate a decrease of propagation losses and polarization sensitivity of polymer waveguide-based devices as a result of thermal treatment. Heating of poly(methyl methacrylate) (PMMA) strip optical waveguides above the glass transition temperature initiates a waveguide surface reflow due to a decrease of a polymer viscosity and surface tension energy. This results in a decrease of surface roughness and shape change from rectangular to cylindrical; thus, scattering losses and polarization sensitivity are minimized.
