This paper presents a novel approach to polishing the end face of optical fibers including single mode fibers. Single mode fibers, due to having small diameters, are cumbersome to hold while polishing against the grinding wheel. The main challenge has been to hold the end face firmly while polishing. Solution to hold it is presented in this study using locally available materials and capillary tubes. The main ingredients used for holding the fiber are capillary tube, due to capillary action, and the sealing wax. Excellent results were achieved and the results were confirmed and are presented in the form of improved coherence length and beam quality.
Keywords: optical fiber, laser beam, end face polish, capillary action.
Представлен новый подход к полировке торцевых поверхностей оптических волокон, включая одномодовые волокна. Малость диаметров одномодовых волокон затрудняет жёсткую фиксацию их торцов по отношению к полировальнику.
Предложен способ, позволяющий решить эту проблему с использованием доступных материалов (уплотняющего воска) и капиллярных трубок, причём фиксация волокон внутри трубок достигается за счёт всасывающих уплотняющий материал капиллярных сил. Экспериментально получено существенное улучшение оптических свойств волокон — увеличение длины когерентности и качества выходного излучения.
Ключевые слова: оптическое волокно, лазерный луч, полировка торцевых поверхностей, капиллярная сила.
