We fabricated a double micro-ring-resonator wavelength-selective filter using the waveguide fabricated by the intermixing of InAs/InGaAlAs quantum dots grown on an InP (311)B substrate. Intermixing was done by using ICP-RIE etching and annealing technique at a low temperature of 650°C. The output-power contrasts of the device were 9.0 dB and 8.6 dB for TE and TM modes, respectively.
This paper reports the fabrication of nanoprobe electrodes based on carbon nanotubes (CNTs) for intracellular recording. The nanoprobe electrodes are cantilevers of single/bundle CNTs with insulating covers and exposed tips. Parylene-coated CNT bridges were cut into probes by physical stretch. CNTs were consequently exposed at the probe tips, because of low friction between CNTs. In this method, only...
