“…A 1 × 2 Y-coupler was fabricated with a cutting and gluing technique as shown in Figure 2. Among the many methods of manufacturing such splitters [50][51][52][53][54][55][56][57], this was chosen as one of the simplest and less time-consuming. The first PMMA fiber was cut at an angle of 90 degrees and two others were cut at an angle of 14 degrees.…”

Pulse wave measurement is a highly prominent technique used in biomedical diagnostics. The development of novel cost-effective pulse wave sensors will pave the way to more advanced healthcare technologies. This work reports on a pulse wave optical fiber sensor interrogated by a smartphone. The sensor performance was tested in terms of signal to noise ratio, repeatability of demodulated signal and suitability of demodulated signals for the extraction of information about direct and reflected waves. The analysis showed that the observed fluctuations of signal parameters are caused by variability of the state of the cardiovascular system and not by the system noise.

“…In this context, multi-port couplers are key elements to implement different layouts that require combining or splitting optical signals, whereas similar designs are needed for sensor applications and for power monitoring in network management and testing [1][2][3]. Thus, depending on their function, several coupler designs based on different technologies have been developed: waveguide plates, injection molding, fused-tapered, thermally bended/glued or misaligned fibers and beam-splitter cubes [4][5][6][7][8]. The main issue when these devices are introduced in a POF link is that they can modify the fiber modal power distribution, changing the transmission performance so that it is necessary to assess and quantify their impact [9].…”

Couplers and splitters are common devices in single-mode and multi-mode glass fibers applications, where they perform a variety of functions. However, when switching to plastic optical fibers (POFs), there is a shortage of commercial devices, which are usually custom-made. The problem with these devices is that modal power distribution in POFs is easily modified by spatial disturbances that produce a localized strong power transfer between modes, thus changing their transmission properties. In this work, a commercial Y-coupler designed for POFs is experimentally characterized. Measurements of its spectral, spatial and temporal characteristics have been performed, including insertion loss as a function of wavelength, angular power distribution, and frequency response. The obtained results show that this device has an equalizing effect over the power spatial distribution that reduces the fiber bandwidth, demonstrating the importance of considering the impact of this type of devices on the transmission properties of any POF system.

Mesin pemotong CO2 laser adalah alat yang digunakan dalam mengerjakan cutting (pemotongan) dan engraving (grafir) beberapa bahan seperti polimer, kaca, kertas, kain dan beberapa bahan non-logam. Mesin pemotong laser CO2 banyak digunakan untuk membuat hiasan di dalam ruangan maupun di luar ruangan seperti papan nama pada beberapa toko, kantor, hotel, perusahaan, ruang pameran, dan beberapa aksesoris seperti tropi, gantungan kunci dan beberapa aksesoris lainnya. Dalam penelitian ini akan dipelajari tentang pengaruh kecepatan pemotongan laser CO2 terhadap bentuk, lebar, dan kedalaman dalam pembuatan kanal mikro (microchannel) pandu gelombang opik pada substrat akrilik. Hasil fabrikasi diamati menggunakan mikroskop optik serta perhitungan lebar dan kedalaman menggunakan mikrometer bergeser. Dari hasil observasi dan analisis fabrikasi, hasilnya menunjukkan bahwa semakin tinggi kecepatan laser CO2 semakin dangkal kedalaman yang dihasilkan. Dalam penelitian ini daya yang digunakan adalah 2,4 W dan menghasilkan kanal mikro dengan kedalaman terkecil 190,91 µm dengan kecepatan laser 100 mm/s dan terbesar 604,17 µm dengan kecepatan laser 50 mm/s. Dari hasil penelitian ini direkomendasikan kecepatan yang baik untuk membuat kanal mikro sebagai aplikasi pandu gelombang optik adalah 95 mm/s dan 100 mm/s dengan daya sebesar 2,4 W.
