Optical communication is accepted as practical when the cost of introducing it is less than that of the conventional electronics. Silicon photonics is the prime candidates for low-cost highly integrated photonic devices because silicon semiconductor industry gives the most cost-effective and highly-integrated devices today. In addition to that, silicon as an optical material offers high-index contrast...
We developed a Si nano-photodiode with a surface plasmon (SP) antenna for a SiON waveguide-integrated structure. We showed that interfacial periodic nano-scale metal-semiconductor-metal Schottky electrodes function as an SP optical antenna and also as an optical coupler between a SiON waveguide and a very thin Si-absorption layer.
We developed a lead zirconate titanate, Pb(Zr,Ti)O3 (PZT), optical waveguide fabricated using aerosol deposition (AD). The device's optical transmission loss of about 4 dB/mm is comparable with that of AD film. The PZT optical waveguide can meet the requirements of optical modulators for low optical loss.
We developed lanthanum modified lead zirconate titanate, (Pb,La)(Zr,Ti)O3 (PLZT), electro-optic modulators on a Si substrate using aerosol deposition (AD) for on-chip optical interconnections. The modulator was designed as a 250 times 300 mum ring resonator with a 7 dB extinction ratio at 3 Vp-p. We observed the optical transmission of a PZT waveguide and the transmission loss was as small as 4 dB/mm.
