Title Raman scattering light amplification device, method for producing raman scattering light amplification device, and raman laser light source using the raman scattering light amplification device
Abstract (TWI619997)
A Raman scattering light amplification device is provided.
The device includes a waveguide formed in a photonic crystal (20) on a semiconductor substrate, in which air holes (20a) are formed.
The waveguide has resonant modes with incident light at multiple frequencies.
Frequency difference between one frequency and another frequency of the multiple frequencies equals to the Raman shift frequency in the semiconductor substrate.
The waveguide is formed along the direction with respect to the crystal plane orientation of the semiconductor substrate such that the Raman transition probability expressed by electromagnetic fields of the two resonant modes and Raman tensors of the semiconductor substrate are maximized.
Scope of claims [claim1]
1. Kinds of Laman diffused light enhancement installments, are in the air gate forms in the photonic crystal on semiconductor foundation plate, has resonating pattern the Laman of diffused light enhancement installment of guided waves road under a plural number frequency regarding the incident light, its characteristic lies in: The above guided waves road crystallizes the position surface formation direction to establish in the above semiconductor foundation plate: A resonating pattern is equal to the Laman displacement frequency of above semiconductor foundation plate with other resonating patterns' frequency differences, and Laman who expressed by above two resonating patterns' the Laman tensor of electromagnetic field distributed and above semiconductor foundation plate jumps the probability to become in a big way.
