(57) ABSTRACT A laser device, in particular a semiconductor laser, emitting optical
radiation With a de? ned mode pattern can be pro duced from a standard Fabry-Perot (FP) …

The invention relates to the field of grating structures. The invention provides a longitudinal
grating having an aperi odic structure, wherein the grating has a selected response …

A method for producing aperiodic gratings and waveguides with aperiodic gratings uses a
simulated annealing process that starts with a random configuration of grating elements and …

Previous descriptions of scanned probe oxidation kinetics involved implicit assumptions that
one-dimensional, steady-state models apply for arbitrary values of applied voltage and …

We report the observation of anomalously high currents of up to 500µA during direct oxide
nanolithography on the surface of n-type silicon {100}. Conventional nanolithography on …

Fabrication of silicon nanostructures is a key technique for the development of monolithically
integrated optoelectronic circuits. We demonstrated that the process of scanning probe …

In this paper we present a systematic study of photonic bandgap engineering using
aperiodic lattices (ALs). Up to now ALs have tended to be defined by specific formulae (eg …

A new method of selectively patterning a silicon substrate with silicon dioxide and silicon
nitride is demonstrated. An oxide patterned silicon substrate is directly nitrided using a …

Silicon that is nitrided in a pure nitrogen plasma is patterned with voltage applied by an
atomic force microscope (AFM). Wet chemical etching into AFM-patterned (110) silicon …

Scanning probe lithography (SPL) and anisotropic tetra-methyl ammonium hydroxide
(TMAH) etching (SPL+ TMAH) were used to fabricate a series of one-dimensional prototype …
