Abstract
1.3μm Electroabsorption Modulated DFB Lasers (EMLs) operating at 45°C are presented for higher order intensity modulation formats. The application of Pulse Amplitude Modulation (PAM) is experimentally demonstrated for PAM4/PAM8 coding at symbol rates of 28 GBd. With integrated impedance matching the low cost EML shows an increased optical modulation bandwidth of 40 GHz. NRZ eyes at 56 Gb/s have been measured with dynamic extinction ratio of > 9 dB which demonstrates the potential of the devices for PAM at higher symbol rates. The EML performance is discussed for application in single channel solutions of direct detection 100G atacomm systems.
