Paper Abstract

This paper reviews III-V semiconductor dry etching technologies established in the past decade for miniaturizing and integrating photonic devices/components and nano-fabrication under development for creating novel photonic structures such as photonic crystal and quantum dots. After briefing the technology requirements for DWDM/OTDM-based Terabit optical communication era in 2005- 2010, advancement of the GaAs- and InP-based smooth and high-aspect-ration dry etching with micrometers -size is reviewed with some applications to dry-etched laser diodes and waveguide devices. Secondly, EB nano-lithography and dry etching technologies for 10- to 100-nm-size structures are reviewed for demonstrating photonic crystal. Challenging application to extremely miniaturized waveguide-based planar light wave circuits is included. Lastly, nano-probe assisted processing of arrayed quantum dots as a 10-nm-size structure is discussed. Achievement of suppressed size fluctuation using this technology will prov8de us with a possibility of large optical non-linearity promising for all-optical switching devices in the OTDM optical communication network system.
