“…For fabrication of the large core bend waveguides with radius 10, 20 and 30 mm (sample #1) we used a similar fabrication process, which has been already presented for large core 1x2Y splitter assembled with 1 mm POF waveguides [24] or 910 µm core optical fibers (FG910LEC Thorlabs Inc.) [19]. Here we made U-grooves with dimensions 750 μm × 750 μm (wide × high) needed for filling with the waveguide material into the 3 mm thick PMMA substrate.…”

We report about properties of large core plastic planar optical bend waveguides. The dimensions of the waveguides were to be compatible with the commonly used plastic optical fiber with diameter 750 µm and the bend radii of the waveguides varied from 30 to 1 mm. The waveguides were made by engraving of a U-groove by using CNC machining into poly(methyl methacrylate) substrate; the waveguide core layers were made of Norland Optical Adhesive UV photopolymer. We experimentally confirmed that fabricated bends may have the total bend losses A for radii 30 mm 4.1 dB/cm at 850 nm, 4.8 dB/cm at 650 nm and 5.63 dB/cm at 532 nm. These bend waveguides are viable for short reach visible and infrared optical communication with easy and low cost installations.

“…In addition to the latter, even other fabrication techniques are also commonly used to realize SPR sensor, i.e. Laser -LIGA technique [25], hot embossing technique [26], computer numerical control machining technology [27,28] and PDMS molding technique [28]. However, even the 3D printing technique turns out to be promising for the optical waveguide fabrication, allowing the rapid fabrication of digital geometry into physical form with micron accuracy [29].…”

In this work, a Surface Plasmon Resonance (SPR) multiparameter sensor for simultaneous determination of refractive index and temperature was manufactured through a novel and low-cost approach. A polymer planar optical structure was realized via inkjet 3D printing, by using photo-curable resins having tailored refractive index for device’s core and cladding, respectively. The multiparameter sensor was fully designed, manufactured, and experimentally tested to check the numerical analyses run on a preliminary phase. In such a way, a temperature resolution equal to about 0.5°C and a refractive index resolution equal to about 2 x 10^-4 RIU were obtained. Next, even a quality control analysis of the 3D printed surface was carried out by following a novel approach that relies on the profile monitoring technique, with the aim to evaluate the suitability of the design and the geometric accuracy control. In addition, thanks to the cost analysis performed through a properly model, it was proved that the multiparameter sensor designed, manufactured and tested satisfies the low – cost requirements, being the estimated cost ~ 23 €, which is an absolutely competitive cost if compared with other traditional sensors. In the end, even the performance of the sensor in terms of bulk sensitivity (equal to about 900 nm/RIU) resulted to be higher than similar devices already presented in the state – of – the – art, thus proving the validity of the developed SPR multiparameter sensor both in economic and performance terms.
