A 1550 nm polarization-insensitive superluminescent diode (SLED) has been demonstrated with >100 mW continuous wave (CW) output power. More than 40 nm FWHM bandwidth of a Gaussian-shape spectrum, and less than 0.7 dB peak-to-peak ripple were also achieved with a polarization dependence of the output power spectrum that is less than 1 dB over 1530-1610 nm.
A 1310nm superluminescent diode (SLED) has been demonstrated with > 80mW continuous wave (CW) output power at 25 0C with a spectral bandwidth of > 60nm and peak-to-peak modulation of < 0.6dB. Low power ( ~ 4 mW), ultrawide bandwidth ( ~ 95nm) SLED can also be realized using the same structure but shorter cavity length.
