摘要： PROBLEM TO BE SOLVED: To obtain a full optical switch whose device length is short, which is actuated with low power and which is constituted so that the time required for turning off the switch does not depend on the softening time of a non-linear effect by constituting a non-linear optical device of plural tertiary non-linear optical elements and controlling the respective elements by plural different control light beams. SOLUTION: The optical induction switch is constituted so that a polarizer P is arranged at the incoming side of two switch materials M1 and M2 which are the tertiary non-linear optical elements and which constitute the non-linear optical device and an analyzer A is arranged at the outgoing side thereof. The control light beam L1 is made incident on the material M1 at the same time as a signal light beam Lin and the control light beam L2 is made incident on the material M2 by leaving time difference as long as a switching action is executed after the signal light Lin is made incident on the material M2 . By using two control light beams L1 and L2 , the high-speed full optical switching action can be executed though the recovery of the non-linear refractive indexes of the materials M1 and M2 are slow.

SOLUTION: A light amplifying glass is formed of specific matrix glass loaded with 0.01 to 10 wt.% erbium so as to be widened in wavelength width of light which can be amplified, wherein the matrix glass is composed of 30 to 80 mol.% Bi2 O3 , 15 to 69 mol.% B2 O3 , 0 to 50 mol.% Li2 O, TiO2 , ZrO2 , SnO2 , and SiO2 , and 0.01 to 10 mol.% CeO2 . A gain can be realized in a wavelength width of 80 nm or above, and an emission intensity peak value corresponding to a gain is 6 or above. B2 O3 is added to the specific matrix glass, whereby glass is prevented from being crystallized when the matrix glass is manufactured, and the matrix glass can be easily formed. The amount of erbium to add depends on the length of a light amplifying fiber, wherein erbium is lessened in loading when the fiber is long, and erbium is increased in loading when the fiber is short.
