ABSTRACTHigh-bandwidth graded-index (GI) polymer optical fiber (POF) and single-mode POF with good mechanical properties were successfully obtained by our interfacial-gel polymerization technique. The bandwidth of the GI POF is about 1 GHz · km which is two hundred times larger than that of the conventional step-index (SI) POF. The minimum attenuation of transmission is 56 dB/km at 688-nm wavelength and 94 dB/km at 780-nm wavelength. The single-mode POF in which the core diameter was 3–15 μ m and the attenuation of transmission was 200 dB/km at 652-nm wavelength was successfully obtained for the first time.

Semiconductor laser diodes are important components for fifth-generation wireless technologies. To meet 5G wireless specifications, ever increasing performance and reliability requirements of each component become necessary to guarantee uptime air service. In this paper, we present highly reliable 25G DFB uncooled lasers that exhibit low threshold current, high single-mode, high bandwidth, and excellent eye pattern for uncooled operations of -40 to 85°C. Ultra-high component reliability is demonstrated to ensure stable operations for 5G mobile communications.

AbstractA novel architecture of bidirectional gigabit signal transport system over long-haul single-mode fiber (SMF) using wavelength division multiplexed passive optical network technique is proposed and demonstrated. In order to offer multimedia services of high bandwidth, four signals of 5 Gbps data rates are externally modulated and transmitted through four channels over 100-km SMF in uplink and downlink. In our proposed scheme, an excellent bit error rate, good

This paper presents the modeling, design, fabrication, and characterization of ultra-low loss 3D optical waveguides integrated on a glass photonic substrate. A novel, single-step process was developed using moving mask lithography to fabricate a single mode optical waveguide with a built-in turning mirror capable of making 40° or 45° turns for vertical grating couplers or photodetectors, respectively. Planar alignment of the waveguide to fiber interfaces enable passive alignment, contributing to system cost reduction. An optical path with 1.1 dB loss from fiber to die was obtained from optical modeling, while the fabrication of single mode waveguides with built-in mirrors at <1° angular control was demonstrated.

<p>The increasing demand in silicon nano-photonics has encouraged many researchers to put more efforts to explore the feasibility of using optics in the communication medium in order to replace the conventional electrical interconnects (EIs). In this paper, we proposed a SOI- based waveguide in the optical interconnect (OI) link at an operating frequency of 1550nm to work as an interconnection path in a circuit. The performance capability of the OI link was tested using a two-stage CE amplifier to work as the interconnection path from the 1st stage to the 2nd stage amplifier. In term of optical performances, the optical waveguide interconnect managed to achieve a single mode condition for a TE mode and fulfill the receiver sensitivity of a photodiode. While, in term of electrical performance, a two-stage CE amplifier is able to produce a high gain, a wide bandwidth and high slew rate. The proposed implementation of the OIs waveguide is succesfully enhance the performance of the two-stage CE amplifier as well as the analog electronic circuit applications.</p>
