“…The measured sensitivities of hybrid APD-based photoreceivers from [12], [13], [18], and [28]- [31] are plotted and show a good fit to the simulated line. It should be noted that a waveguide APD, which removes the tradeoff between transit times and absorption efficiency, is used to achieve the record result of 19 dBm at 40 Gb/s [12].…”

“…Data from [6] and [24] for the HPT, [6], [7], and [25]- [27] for the PIN-HBT, and [12], [13], [18], [28]- [31] for the APD-HBT have been plotted to compare with experimental data. The differences between calculation and experimental data up to 20 Gb/s are within 1 dB for the HPT and PIN-HBT receivers, which seems reasonable given that measured sensitivity values can vary by as much as 1 dB between identical channels of a PIN-HBT photoreceiver in [32].…”

Abstract-A charge control model was used to simulate the sensitivity and responsivity in a range of photodetector configurations including heterojunction bipolar phototransistors (HPTs), PIN-HBT, and APDs. Our simulations enabled for the first time a direct comparison of the performance between these photodetectors to be made. Simulations have been performed at bit rates from 2 to 40 Gb/s using various combinations of device design parameters (layer thickness, source resistance, and dc base voltage).For a BER =1 0 9 at 40 Gb/s the best sensitivity of approximately 20 dBm was achieved using an optimized APD-HBT configuration, followed by sensitivities of approximately 14 dBm using optimized PIN-HBTs and HPTs. These results were found to agree well with published experimental data.

“…Calculation of the σ bn and σ s can be found in [30] and [36]. In addition, we used the p-i-n FET receiver designed in [45], which has an input noise current equal to 10 pA/ √ Hz. To obtain the optimum number of beams that can be generated with BER not exceeding 10 −9 , we placed the imaging receiver at the room centre (2 m, 4 m, 1 m) as the distance between the transmitters and the receiver is maximum at this location.…”

CGH for Indoor Visible Light Communication System

et al. 2017

In this paper, we propose, design, and evaluate two indoor visible light communication (VLC) systems based on computer generated holograms (CGHs); a simple static CGH-VLC system and an adaptive CGH-VLC system. Each transmitter is followed by the CGH, and this CGH is utilized to direct part of the total power from the best transmitter and focus it to a specific area on the communication floor. This leads to reduction in inter-symbol interference and increasing in the received optical power, which leads to higher data rates with a reliable connection. In the static CG11H-VLC system, the CGH generates 100 beams (all these beams carry same data) from the best transmitter and directs these beams to an area of 2 m × 2 m on the communication floor. In the adaptive CGH-VLC system, the CGH is used to generate eight beams from the best transmitter and steer these beams to the receiver's location. In addition, each one of these eight beams carries a different data stream. Whereas in the first system, a single photodetector is used (added simplicity), an imaging receiver is used in the second one to obtain spatial multiplexing. We consider the lighting constraints where illumination should be at acceptable level and consider diffusing reflections (up to second order) to find the maximum data rate that can be offered by each system. Moreover, due to the fact that each beam in the adaptive CGH-VLC system conveys a different data stream, co-channel interference between beams is taken into account. We evaluate our proposed systems in two different indoor environments: an empty room and a realistic room using simple on-off-keying modulation. The results show that the static CGH-VLC system offers a data rate of 8 Gb/s while the adaptive CGH-VLC system can achieve a data rate of 40 Gb/s.
