초록

평판 도파로에서 Cerenkov-idler configuration 형태의 광학적 매개증폭에 대해서 결합모드 이론을 적용하여 결합모드 방정식을 유도하고, 이 방정식의 근사해를 펌핑광의 고갈(depletion)이 없는 경우에 대해서 구한다. 이 근사해로부터 발생되는 idler의 체렌코프 복사각이 $0^{\circ}$도에 접근할 때 signal의 이득이 크게 향상될 수 있음을 보여주고 수치적 예를 보인다.

Optical parametric amplification has been analyzed for the Cerenkov-idler configuration in planar waveguides. The coupled-mode theory is employed for the analysis. The coupled-mode equations are derived and the approximate analytic solution is obtained for no pump depletion. From the analytic solution, it is shown that the signal power gain can be enhanced as the Cerenkov radiation angle of the idler approaches to zero. The numerical example is also shown for the effect of the Cerenkov radiation angle approaching zero.
