We have modeled the response of a nonlinear periodic structure by means of the Abeles 2×2 matrix method. Our structure differs from the usual rejection‐band filter designs, in that we have chosen the filter elements to be index matched in the abse

Infrared excitation spectra were measured for the p3/2 lines of gallium in silicon. Two missing lines were observed, and a previous weak or doubtful one was confirmed. Spectra were also obtained of the p1/2 lines of gallium and indium in silicon, dem
