    Monolithic integration of continuous-relief diffractive structures with vertical-cavity surface-emitting lasers2003In: IEEE Photonics Technology Letters, ISSN 1041-1135, E-ISSN 1941-0174, Vol. 15, no 3, p. 359-361Article in journal (Refereed)
    Abstract [en]

    In this work, we have studied the transfer of diffractive optical elements (DOEs), originally made in resist, into GaAs for monolithic integration with vertical-cavity surface-emitting lasers (VCSELs). The DOEs are blazed gratings and Fresnel lenses, and have been fabricated on the back surface of bottom emitting VCSELs using electron-beam lithography or replication by hot embossing in resist followed by a quick-dry etch step. Diffraction efficiency was measured to be 81% in the first order of diffraction for the blazed grating.

    All-Fiber Nanosecond Gating for Time-Resolved Spectral Analysis2016In: IEEE Photonics Technology Letters, ISSN 1041-1135, E-ISSN 1941-0174, Vol. 28, no 8, p. 829-832Article in journal (Refereed)
    Abstract [en]

    We demonstrate the addition of time gating to a standard optical spectrum analyzer (OSA) operating in the spectral region similar to 1.06 mu m. This is accomplished by opening for 7 ns the optical input to the OSA with an electrically driven poled fiber in a Sagnac loop. The sequential interrogation with nanosecond resolution of the reflection from three fiber Bragg gratings along a piece of fiber allows distinguishing the spectral peaks created with a minimum separation of 85 cm. The passive extinction ratio of this device is >40 dB and returns to >40 dB from >23 dB on a 35-ns time scale directly after time gating.
