Abstract

A $1.2\mu \mathrm{m}\left(\text{height}\right)\times 125\mu \mathrm{m}\left(\text{depth}\right)\times 500\mu \mathrm{m}\left(\text{length}\right)$ microslot along a fiber Bragg grating was engraved across the optical fiber by femtosecond laser patterning and chemical etching. By filling epoxy in the slot and subsequent UV curing, a hybrid waveguide grating structure with a polymer core and glass cladding was fabricated. The obtained device is highly thermally responsive with linear coefficient of $211\mathrm{pm}∕°\mathrm{C}$.
