“…The self-aligned optical coupling of SOLNET was first demonstrated using two single-mode optical fibers, which are separated with a 400 μm distance and put in a photopolymer with a counter direction. Write beams from a high-pressure mercury lamp were introduced into the photopolymer from the two optical fibers to construct a coupling waveguide connecting the optical fibers with lateral misalignments of 1-9 μm automatically [34,36].…”

We simulated self-organized parallel waveguides constructed from two parallel input waveguides with a core width of 600 nm in a photopolymer using the finite-difference time-domain method. When write beams of 400 nm in wavelength are introduced from the input waveguides 4 μm apart, straight parallel waveguides are constructed in the photopolymer. When decreasing the distance between the input waveguides, the parallel waveguides attract each other and finally merge. By putting 600 nm wide luminescent objects at the waveguide destinations, self-organized parallel waveguides targeting the objects are constructed to pull them back to the correct destinations. The self-aligned parallel coupling waveguides are constructed even when a misalignment of 900 nm exists between the input waveguides and the luminescent objects. For write beams of 650 nm, the allowed misalignment increases due to increased divergence angles.

“…Moreover, bidirectional light irradiation enables automatic optical coupling between two optical fibers, which is called an "optical solder". 9) Further, various extended technologies based on LISW optical waveguides have been demonstrated, [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] and there is a wider range of applications of LISW optical waveguides.…”

We demonstrate a near-infrared (NIR) light-induced self-written (LISW) optical waveguide between graded-index (GI) glass optical fibers with a 50-µm core size (50GIFs) using gel material. We describe the optical properties of the LISW optical solder in terms of its flexibility, adhesiveness, and loss. The results demonstrate that the two 50GIFs were self-coupled through the LISW optical waveguide, and the connection maintained adhesiveness against displacement. A low loss and relaxation of alignment tolerance were demonstrated for the optical interconnection between two 50GIFs using flexible LISW optical soldering. This technology is applicable to future autonomous driving systems using high-speed optical data transmission.

“…Two-beam-writing self-organized lightwave network (SOLNET) shown in Fig. 1(b), which we invented previously, [2][3][4][5][6] is useful for the self-organization of optical waveguides. Two optical devices such as optical waveguides are put in an opposite configuration and a photo-refractive material such as photo-polymers is placed in between.…”

“…To simplify the SOLNET fabrication process, we proposed R-SOLNET, [2][3][4][5] in which the write beams from one of the two optical devices are replaced with the reflected write beams from a reflective material such as a wavelength filter and a mirror on the core facet of the optical device. We simulated R-SOLNET formation using the beam propagation method (BPM), and found that R-SOLNET provides a feasible way to form self-aligned coupling optical waveguides.…”

In a reflective self-organized lightwave network (R-SOLNET), an optical waveguide and optical devices with reflective materials on their core facets are placed in a photo-refractive material, whose refractive index increases with write beam exposure. By introducing write beams from the waveguide, self-aligned waveguides are formed between them by the “pulling water” effect induced by the reflected write beams from the reflective materials. R-SOLNET was formed between an optical fiber and an Al micro-mirror with an angular misalignment of 3°, or an offset of 30 µm. Finite difference time domain calculations revealed that Y-branch R-SOLNET is formed by placing two reflective materials.
