✦ Synopsis

A simple and cost-effective tunable single-mode laser is proposed and experimentally demonstrated using FP-LD which inherently oscillates at multi wavelengths. As the operating temperature changes, the peak wavelength hops by an amount of FP-LD mode separation and overall tuning range is about 10 nm with side mode suppression better than 27 dB.

## Abstract A new architecture of dual‐stage erbium‐doped fiber amplifier with double‐pass preamplification is successfully demonstrated. A maximum gain of 52 dB is obtained at −50‐dBm signal power with 1550‐nm signal wavelength. An efficient filtering of amplified spontaneous emission improves gai
