Abstract: The present disclosure includes methods for evaluating the bending stiffness of high aspect ratio nanosized structures. One example method for evaluating a bending stiffness of high aspect ratio nanosized structures arranged in a plurality of test patterns produced by lithography and etching in a respective plurality of different areas of a semiconductor substrate, where each test pattern includes a regular array of the high aspect ratio nanosized structures, includes scanning the regular arrays in the plurality of test patterns by an electron beam produced according to a same set of beam conditions for each array. The method also includes deriving images of the regular arrays in the respective test patterns by electron beam microscopy. Additionally, the method includes determining from each of the images an e-beam induced collapse rate representative of a percentage of structures in each array that have collapsed under an influence of the electron beam scanning.

Abstract: Examples include a tunable laser, in particular, an external cavity type laser. Examples also include a method of operating the tunable laser. The tunable laser is designed for fast and repeatable wavelength tuning over a wide wavelength range. The tunable laser includes a cavity and a gain medium arranged in the cavity. The gain medium is configured to generate light by stimulated emission and to emit the light into the cavity. The tunable laser also includes a laser output configured to output a portion of the light in the cavity as a laser beam. The cavity includes a first resonator and a second resonator that are optically coupled to each other. A resonance frequency of the first resonator is tunable. A free spectral range (FSR) of the second resonator is an integer multiple of an FSR of the cavity.
