Heart and breath rate are fundamental vital signs used for early detection in cardiac events. In this work, a sensor based on singlemode-multimode-singlemode (SMS) fiber structure was designed, fabricated, and tested for simultaneous measurement of heart and breath rate on a bed. A signal processing was used for obtaining the heart rate from the output signal of SMS fiber structure. In order to reduce noise in the heart rate signal, a Butterworth filter was employed. The results show that the proposed SMS fiber structure as a sensor has a relative error of 11% and 6% for measuring the heart and breath rate, respectively. The SMS fiber sensor gives a potency to measure the heart and breath rate simultaneously on a smart bed and suitable to be used in home and hospital.

This paper presents a Thulium (Tm) doped fiber amplifier operating in 1800nm region. We demonstrated a small and compact footprint of optical amplifier architecture with only 20cm length gain fiber. Ytteria nano-particles functioning as a modifier allows high Tm concentration thus increase Tm solubility in optical fiber. A wide amplification window of 100nm is obtained with maximum gain up to 24.2 dB and noise figure (NF) as low as 5.5 dB.

Radio over fiber with visible light communications (RoF-VLC) can be a pioneering technology to provide ubiquitous wireless access for indoor wireless communication. In this paper, we propose a new RoF-VLC system using 10km fiber and multiple LEDs for indoor VLC through simulation. Gray coded input sequence with either On-Off Keying (OOK) or 16 QAM-OFDM modulated was used for data transmission. Radio signals transmit 1.5 Gb/s and 2.5 Gb/s data using OOK and16 QAM-OFDM, respectively. The signal from the 10 km fiber is sent to an access point with red, green, blue and yellow (RGBY) LEDs each with ~50 MHz modulation bandwidth. Filters such as Gaussian, Bessel, Trapezoidal, and Rectangle are used to increase the modulation bandwidth of LEDs. The maximum data rates that can be achieved at the VLC receiver is 400 Mb/s and 3.2 Gb/s using OOK and 16QAM-OFDM, respectively. The effect of filters and beam convergence on BER is also measured in this paper. Beam convergence is important for short range applications. The results obtained using the RoF-Vlcproposed in this paper are better compared to the ones in previous works in this area.

A Europium Aluminum Benzyl Methacrylate (Eu-Al/BzMA) integrated optical waveguide with 50 $mumathrm{m}$ graded-index multimode circular core is fabricated by applying the Mosquito method for the potential application of optical interconnect. The parabolic index profile of the waveguide core is measured to confirm the profile exhibited by the waveguide. A preliminary experiment of the signal transmission is performed at 26 Gb/s to evaluate its capability in high dense and speed optical interconnections. According to the results, the waveguide successfully demonstrated free bit-error-rate through 5 cm waveguide transmission.

Monte Carlo simulation of an optical light propagation in a developed tapered multimode fiber sensor for the detection of salinity solution is demonstrated. The effect of the changes of the length of the sodium chloride in the tapered fiber region as a function of the concentration/absorption coefficient on the absorbance response are observed. Results showed the linear relationship of the absorbance with the length of the sensing solution as well as with the absorption coefficient. The sensitivity of the system is calculated to be less than 0.0058 a.U/mm. The findings exhibited the potential of the Monte Carlo simulation as a platform for a preliminary study of tapered fiber sensor applications.

A low-cost temperature sensor using D-shaped optical fiber with 1.7m long, highly concentrated erbium-doped fiber as the gain medium, has been experimentally demonstrated. The D-shaped optical fiber was polished using a 5V DC motorized mechanical wheel and interacted with surrounding temperature varying from room temperature to $70^{circ}$ C. Due to the temperature changes, the wavelength shifted to a longer region. This sensor has a sensitivity and linearity of 8.6 $mathrm{x}10-3$ dBm/% and 94%, respectively. By using a simple fiber ring laser cavity, a sensitive and stable temperature sensor was successfully achieved.

This paper demonstrates a multiwavelength fiber laser (MWFL) using different types of semiconductor optical amplifiers (SOAs) in conjunction with Lyot filter as comb filter. Three different SOAs were compared; linear, non-linear and booster optical amplifier (BOA). The multiwavelength generation using BOA had produced the best performance with extinction ratio (ER) of 52dB and peak power of −13.2dBm.

All fiber temperature sensor based on $mathrm{MoWS}_{2}- mathrm{rGO}$ coated tapered fiber is demonstrated. The large evanescent field of tapered fiber allows $mathrm{MoWS}_{2}-mathrm{rGO}$ coated tapered fiber to absorb the surrounding heat and changes the refractive index of $mathrm{MoWS}_{2}-mathrm{rGO}$ coated tapered fiber. The refractive index change is due to thermo-optic effect. When there is a change of surrounding temperature, the refractive index of the coated tapered fiber changes and this subsequently alters the incident light polarization. The sensitivity of the proposed temperature sensor is measured at 0.63°/°C. This is the first demonstration of using $mathrm{MoWS}_{2}-mathrm{rGO}$ tapered fiber as temperature sensor.

We have developed a microscope that overcomes the limitations of using a focused electron beam. A superresolution optical microscope using a nano-sized optical spot generated by irradiating an ultra-thin luminescent film with an electron beam was shown. A high spatial resolution chemical sensor that visualizes the ion concentration distribution has also been developed. By applying an electron beam with high convergence in this way, it is possible to develop a microscope with high spatial resolution beyond the diffraction limit.

In orbital angular momentum (OAM) based free-space optical (FSO) communication systems, a CCD camera can be used at the reception side to capture images of the laser beam carrying the transmitted OAM modes. The tasks of extracting features from these images and identifying the transmitted modes are studied in this paper. The ability of machine learning algorithms to perform these tasks is explored. Laguerre-Gauss beams and turbulent channels are considered. Different modulation alphabets formed by using sets of superposed and multiplexed OAM modes are investigated. Appropriate choice of these alphabets can increase data rate transmission.
