    • A method for detecting surface and bulk deep states in semiconductor materials is provided. In various embodiments, the method comprises configuring a detection circuit of charge based deep level transient spectrometer in one of a parallel mode and a series mode by controlling the configuration of a switching circuit of the detection circuit. The method additionally comprises generating digitized voltage charge outputs of a device under test utilizing the detection circuit as controlled via execution of an analog-to-digital conversion and timing program by a control system of the charge based deep level transient spectrometer. Furthermore, the method comprises obtaining desired information about deep level transients of the device under test based on the digitized voltage charge outputs via execution of a control system operable to execute a Q-DLTS data analysis program by the control system.

    • A microresonator structure comprises a waveguide and a microsphere. The waveguide is of elongated cylindrical shape and includes a first section of optical transmission material and a cavity section axially aligned with the first section. The cavity section includes a first cavity and a second cavity. The first cavity is adjacent to the first section and includes a first sidewall of optical transmission material with an inner surface that tapers inward to an apex positioned adjacent to the first section. The second cavity is positioned adjacent to the first cavity of hollow cylindrical shape and includes a circumferential second sidewall of optical transmission material that abuts the first sidewall. The microsphere has a spherical outer surface and is positioned within the cavity section such that the outer surface contacts a portion of the first sidewall and a portion of the second sidewall.
