Literary work is one of language usage that made to give pleasure and enjoyment to the reader. Poetry and music are kind of litarary work. Song is the combination between poetry and music. The purpose of this study is to find out the general meaning, the detailed meaning, and the message inside the lyrics poem “How Many Hours” Michael Learns to Rock’s song. This study uses descriptive qualitative method as the research design because there is no treatment in this study as in experimental research. The approach that is used in this study is objective approach because this study does not concern with the author’s experience and life. The object of this study is the lyrics of “How Many Hours” in Michael Learns to Rock’s song , because it contains general meaning, detailed meaning and the message inside.

Nonlinear adiabatic optical isolator

We theoretically propose a method for optical isolation based on adiabatic nonlinear sum frequency generation in a chirped quasi-phase-matching crystal with strong absorption at the generated sum frequency wave. The method does not suffer from limitations of dynamic reciprocity found in other nonlinear optical isolation methods, and can provide tunable optical isolation with ultrafast all-optical switching capability. Moreover, as an adiabatic technique it is robust to variations in the optical design and is relatively broadband
