Silica optical microresonators
Jelínek, M. ; Todorov, Filip ; Matějec, Vlastimil ; Chomát, Miroslav ; Kubeček, V. ; Berková, Daniela
The paper deals with the preparation of spherical silica microresonators by melting silica optical fiber with an oxygen-hydrogen flame. Resonant spectra of prepared spherical silica microresonators suitable for telecommunications and sensors purposes are also presented.
Optical microresonators for sensing and communications
Todorov, Filip ; Matějec, Vlastimil ; Chomát, Miroslav ; Berková, Daniela ; Jelínek, M. ; Kubeček, V. ; Sedlář, R.
The paper deals with optical microresonators, their preparation, characteristics and application to telecommunication and sensor purposes. Results in the preparation and characterization of spherical silica resonators achieved by the authors are presented.
Mřížky s dlouhou periodou v jednovidových optických vláknech zhotovené pomocí CO.sub.2./sub. laseru
Todorov, Filip ; Dunovský, J. ; Kolařík, L. ; Císařovský, P. ; Chomát, Miroslav ; Berková, Daniela ; Matějec, Vlastimil ; Kašík, Ivan
The inscription of LPGs with a period of 0.17 up to 0.98mm with a focused CO.sub.2./sub. laser beam into an experimental non-commercial optical fiber under a variety of conditions is reported. The reproducibility of the LPG’s inscription process and an experiment with multiple inscription of LPGs are presented.
Výroba mřížek s dlouhou periodou v optických vláknech pomocí záření CO.sub.2./sub. laserového paprsku
Císařovský, P. ; Dunovský, J. ; Kolařík, L. ; Todorov, Filip ; Chomát, Miroslav ; Berková, Daniela ; Vrbová, M. ; Jančárek, A.
Inscription of the LPGs by a focused CO.sub.2./sub. laser beam in step-index fibers is reported. The transmission spectra of the LPGs fabricated in optical fibers drawn at 1880.sup.o./sup.C and 1930.sup.o./sup.C. under several inscription conditions are shown. The results indicate strong dependence of the LPG spectra on the conditions of the fiber drawing process and of the LPG fabrication. The first results of the preparation of a new type of a graded-index fiber for the LPG fabrication are reported too.
