“…5. It should be noted that, due to the presence of the crosstalk effects between the neighboring LED arrays [39], the outward and return signals can not be communicated at the same time in our communication systems. This issue could be addressed by building a half-duplex time-division duplexing (HD-TDD) communication system, as reported in Ref.…”

The feasibility of using InGaN/GaN multiple-quantum-well light-emitting diode arrays (LED arrays) as photodiodes (PDs) is investigated experimentally in addition to their light emitting function. Two discrete LED arrays are produced from one 4 × 4 LED array with a parallel-connected pixel configuration. Such compact designs are useful for light emission or detection at the transmitting/receiving terminals of optical wireless communication systems. Despite 4 × 2 LED arrays achieving a light output power of 67.4 mW at 250 mA, they exhibit an optical responsivity (detectivity) of 0.183 A/W (1.61 × 1012 cm Hz 1/2 W −1 ) under ultraviolet light illumination (λ = 380 nm) at zero bias. For 4 × 2 LED arrays, the presence of an appreciable ultraviolet light response, together with a high 3-dB bandwidth (~8 MHz) for modulated light detection, allowed us to build a 15 Mbit/s directed optical link with these LEDs functioning as both the optical transmitter and the receiver. Finally, the unitary LED array-based optical link is capable of real-time transmission of digital audio signals (data rate = 6 Mbit/s) at a propagation distance of 100 cm in free space even though some of the constituent pixels are inactive for light detection.

“…Planar hybrid optical integration using, for example, silicon optical bench technology holds the promise of lowering the cost of the optical modules by simplifying the passive alignment and reducing the assembly steps; prototypes of hybrid integrated optical modules on a planar lightwave circuit (PLC) platform have been demonstrated. 23 Indeed, waveguide integration allows the realization of complex optical functions and enables the assembly of the best of both optoelectronic and integrated circuits (ICs) on the same substrate. However, the small module size achieved by hybrid integration makes achieving the required levels of optical and electrical isolation difficult.…”

“…As the optical transceiver module becomes more compact, the communication devices must be closely packed in one package, and further crosstalk reduction becomes necessary. To satisfy these demands, research has addressed the hybrid integrated module that is unified to the SiO 2 system that formed optical and electrical devices on a silicon substrate [2][3][4][5].…”

SUMMARYWe developed a 1.3/1.55-µm optical transceiver module for use in asynchronous transfer mode-passive optical network (ATM-PON) systems, which is the global standard for optical access networks. A compact, low-cost module was implemented by mounting the active devices such as optical devices like laser diodes (LDs) and photodiodes (PDs), and integrated circuits, and the passive devices such as optical waveguides, wavelength division multiplexing (WDM) filters, and optical fibers on the surface of a silicon (Si) bench. We adopted the simplest waveguide, the straight waveguide, to achieve the best repeatability by the SiO 2 waveguide and developed a double-filter photodiode to lessen optical crosstalk. The results achieved an output of 0 dBm from the optical fiber to 1.3 µm at 155.52 Mbit/s and a -40 dBm minimum receiver sensitivity at 1.55 µm during full-duplex communication, and demonstrated the effectiveness of this transceiver module design.
