“…It provides excellent temperature profile also at low temperatures given radiation resistant [16]. Sapphire FBG is used as a temperature sensors up to 1600 0 C [18][19][20][21][22][23][24][25][26][27][28][29]. The Bragg wavelength with the grating period and effective fiber index is [7,[30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49] Temperature and strain induced Bragg wavelength shifted shown as [15,[34][35][36][37][38]:…”

This study has outlined the fiber bragg grating (FBG) temperature sensors signal processing for data communications by using OptiGrating simulation software. The reflectivity of the silica and sapphire fiber grating spectrum is reported against the grating wavelength for internal and external temperature variations. As well as apodized Gaussian reflectivity of the silica and sapphire fiber grating spectrum is simulated and clarified against the grating wavelength for high temperature variations. The temperature sensitivity of sapphire FBG nearly 0.11 pm/0C, where its value is three times higher than silica FBG. It is observed that silica and Sapphire FBG sensors were tested up to 1000 0C by using Gaussian apodization type, side lobes in reflectivity spectrum are totally suppressed.

Optical Communication system consists of three main blocks, such as a transmitter, a transmission channel and a receiver. The modulation and demodulation techniques are the most important for the transmitter and receiver, respectively, to transmit and receive the useful information to the longer distance without compromising the minimum error, maximum Q factor and also maintaining sufficient power and other parameters at the receiver to reproduce the original signal with minimum noise and distortion. A hybrid modulation technique is used which will optimize the merits of both digital and analogue modulation. Moreover, the impact of amplification at the transmitter and receiver has been studied and analyzed. The present paper highlights the design of various hybrid modulation techniques mainly DPSK-FM and QAM-FM in this context. Furthermore, the evaluation and performance analysis of various designed systems in terms of Q factor, bit error rate and the number of users and received power has been done.

“…Optical communication system should satisfy the following basic specifications such as determination of transmission type (analog/digital); achieving the system fidelity (higher SNR/lower BER); larger transmission bandwidth (BW); longer repeater spacing (span); less cost of system installation; reliability (error-free transmission); less cost of system maintenance; and less of complexity [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. While selecting a photodetector, the following factors are considered such as minimum optical power that must fall on photodiode to satisfy BER at specified data rate; less complexity of circuit; less cost of design; and less bias requirements [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35].…”

This article clarified the basic fiber Bragg grating (FBG) apodization functions effects on the filtered optical acoustic signal (AS). Max optical acoustic power variations after acousto optic filter is clarified with the spectral wavelength variations. FBG apodization functions are uniform, Gaussian, and Tanh. We have tested the max optical acoustic power variations after various apodization FBG functions with the spectral wavelength variations. The max AS power amplitude after the electrical combiner is reported based various Apodization FBG functions. The max optical AS after FBG is studied with various FBG lengths for various FBG apodization functions at the central wavelength of 1.55 μm. The max electrical power after power combiner unit is demonstrated with different FBG lengths for various FBG apodization functions at the central frequency of 193.1 THz.
