• An uncoated tapered hemispherical-end fiber microlens, formed by etching a single-mode fiber in a hydroflouride solution, is spliced with a fiber grating to form an external cavity for a 1.55 μm fiber grating laser (FGL). The fiber microlens provides a coupling efficiency of more than 65% between the semiconductor laser and the fiber grating external cavity. The FGL has spectral characteristics of a single line ($\lambda_{0}=1555.6$ nm), a single longitudinal mode ($\mathrm{SMSR}>30$ dB), and a high output power (${>}1$ mW). However, the $\mathrm{SMSR}$ shows a current-dependent oscillation, which can be consistently explained by calculating the rate equations of an equivalent external cavity model on the FGL.
