Packaging investigation of optoelectronic devices

Abstract

Compared with microelectronic packaging, optoelectronic packaging as a new packaging type has been developed rapidly and it will play an essential role in optical communication. In this paper, we try to summarize the development history, research status, technology issues and future prospects, and hope to provide a meaningful reference.

Structural, Electronic and Optical Properties of S-Doped Anatase TiO₂

“…The space group of anatase TiO 2 is I4 1 /amd and the local symmetry is the 19 4h D . We have obtained, through a total energy minimization process, the values a=3.7846 Å and c=9.7072 Å, which are slightly larger than a=3.692 Å, c=9.471 Å [2], and closer to the values a=3.80315 Å and c=9.55847 Å [3]. The experimental values are a=3.782 Å and c=9.502 Å according to the data of Burdett et al [11].…”

“…Since the discovery of photo-electrochemical splitting of water on TiO 2 [1], TiO 2 photocatalyst has received special attention as a promising photocatalytic semiconductor. Moreover, TiO 2 has been widely studied both experimentally and theoretically because of its excellent functionality, long-term stability, nontoxicity, wide band gap, unique optical and electronic properties, and low cost [2,3]. Specially, anatase structure has been proven to be the most promising photovoltaic solar cells and photocatalysis [4].…”

1.5 μm, 8?×?12.5 Gb/s of hybrid-integrated TOSA with isolators and ROSA for 100 GbE application

“…In order to match with the 50 Ω system, the characteristic impedance of the CPW transmission lines should be designed to be 50 Ω to reduce electrical reflections. This can be determined as follows [17,18] :…”
