1.8 μm broadband light source using super luminescent diode

The first light source with a broadband spectrum in the 1800 nm wavelength region has been developed by employing a cascade configuration with a 1.65 μm band super luminescent diode and a Tm3+-doped fibre amplification unit. The achieved bandwidth where the intensity exceeded -20 dBm/nm was 247 nm (...

Description
Summary:The first light source with a broadband spectrum in the 1800 nm wavelength region has been developed by employing a cascade configuration with a 1.65 μm band super luminescent diode and a Tm3+-doped fibre amplification unit. The achieved bandwidth where the intensity exceeded -20 dBm/nm was 247 nm (from 1611 to 1858 nm) with a low ripple, whose peak-to-peak value was
