Low the expansion by the phonon which dopes dysprosium energy glass wave guide

摘要

(57) Abstract Expansion method, the laser and the expansion optical communication system which are based on the optical glass amplifier and the above-mentioned amplifier are disclosed in this bill, these, have or less the phonon energy of everything and approximately 350cm-1, at the same time, it has been based on the single - mode glass of the length which is doped, was produced dysprosium from the glass which is limited. As for this glass, 0.1-30 the mol % X and 0-40 the mol % arsenic, 0.01-20 the mol % gallium, 40-85 the mol % Y and 0.001 - 2 weight % it contains dysprosium (at the time of describing, as for X it is chosen from blend of germanium and germanium and up to 50% sulfur, it is chosen from selenium, indium and these blends,) Y. It connects the above-mentioned system, with the coupler and said coupling device and the silica based fiber which conveys the optical signal which it should expand, the pump light ray source which it is connected with the aforementioned coupling device, it consists of the other silica based fiber which it is connected with the amplifier in the amplifier and its other end which it is connected with the above-mentioned coupler in on the one hand end. The above-mentioned expansion method introduces the optical signal which it should expand into the coupler, the pump light ray introduces into the above-mentioned coupling device, makes with the optical signal and the pump optical signal connect, introduces the optical signal which is made to connect into the amplifier, making the above-mentioned optical signal expand by making the electron in dysprosium excite, consists of the process which from the said optical signal it makes discharge at approximately 1.3 millimicrons.
