Abstract:
The present invention may provide a structure capable of obtaining a higher difference in refractive indices between that of a transparent material and that of a cavity, than in the past, and a manufacturing method thereof, and the present invention provides a structure having a transparent material and an internal cavity which is formed by irradiating said transparent material with a pulse laser beam having a pulse width of 10×10−12 seconds or less, and wherein refractive index of said transparent material at d line is nd≧1.3.
