Abstract
Electroabsorption modulators with polarisation independence of chirp and transmission (TE/TM sensitivity <0.4 dB at 1550 nm) over a wide wavelength range from 1540 nm to 1560 nm have been realised using tensile strained InGaAsP quantum wells. The fabricated devices show 42 GHz modulation bandwidth and 1.8 V drive voltage, resulting in a high bandwidth-to-drive-voltage ratio of 23.3 GHz/V.Keywords
