Bend-resistant leaky multi-trench fiber with large mode area and single-mode operation. [PDF]
A novel structure of modified multi-trench fiber (MTF) with characteristics of bend-resistance and large mode-area is proposed. In this structure, each low refractive-index trench of traditional MTF is broken by two gaps up and down.
