Very recently, the 2μm wavelength region is attracting growing attention as a potential new transmission window for optical communications to accommodate the ever-increasing internet traffic. This is underpinned by the emerging technology of hollowcore photonic bandgap fibers (HC-PBGFs), which holds great promise as a transmission medium with predicted ultra-low loss window around 2 μm. In order to realize optical communications at 2 μm, high quality optical amplifiers are indispensable. The first part of this thesis focuses on the development of thulium doped fiber amplifiers (TDFAs) for 2μm optical communications. To start with, a fiber laser pumped TDFA is developed. It provides high gain (>35 dB), noise figure (NF) as low as 5 dB, and over 100nm wide bandwidth around 2 μm. As a crucial step forward, diode-pumping scheme of TDFAs is investigated. Amplification in the range 1810.
