We demonstrate an add/drop filter based on coupled vertical gratings on silicon. The concept is extended to implement a 1 by 4 wavelength division multiplexer with 3nm bandwidth, 1dB insertion loss and 16dB crosstalk suppression.
In this paper, we present experimental results of frequency scaling and transducer optimization in internal dielectrically transduced silicon bar resonators. We show that selective positioning of the dielectric transducers inside the resonator can preferentially excite targeted harmonics while suppressing undesired modes. Furthermore, measurements across multiple resonators show lower motional impedance...
A cladding-modulated Bragg grating implemented using periodic placements of silicon cylinders in the cladding along a silicon waveguide is proposed. Modeling results are verified experimentally, demonstrating coupling strengths differing by an order of magnitude.
We evaluated profiles of B, P, As, and Si implanted in Ge substrates by secondary ion mass spectrometry, analyzed the profile data using a quasi-crystal Lindhard-Scharff-Schiott (QCLSS) theory, tuned its parameters, and established a corresponding database based on a tail function. We also predicted Ge, Sb, Ga, In, and Xe profiles in Ge substrates by using the QCLSS theory and also established a corresponding...
We demonstrated for the first time the device performance of (110) nMOSFETs featuring a Si migration process, resulting in better mobility and modified shape of the narrow active region, and ultra-shallow Al implantation after nickel silicide (NiSi) formation, resulting in reduced parasitic resistance. We found that these processes made the performance of (110) nMOSFETs competitive with that of (001)...
