After examining Harmony Korine's feature films, shorts, art installations, music videos, paintings, and novel, a clear pattern of stereotyping and misappropriating African American aesthetics emerges. This thesis addresses the mass appropriation of h

For optical pulse incidence as compared with continuous-wave incidence, the enhancement of two-photon absorption inside a high-finesse planar microcavity is reduced, the pulse inside the cavity and the cavity spectrum are broadened. The analysis show

Chromatic dispersion monitoring based on two-photon absorption (TPA) in semiconductors is very attractive because it does not need any high speed electronic devices (Inui, 2002). However, at present the dispersion monitoring range is limited to half

In: CLEOE-IQEC 2007-European Conference on Lasers and Electro-Optics and the International Quantum Electronics Conference, 17-22 June 2007, Munich, Germany.
Two Photon Absorption (TPA) is a non-linear optical-to-electrical conversion process that can be significantly enhanced by placing the active region within a resonance microcavity. The experiment confirmed the potential use of the microcavity structu

Due to the introduction of new broadband services, individual line data rates are expected to exceed 100 Gb/s in the near future. To operate at these high speeds, new optical signal processing techniques will have to be developed. This paper will dem
