Highly reliable and high yield 1300 nm InGaAlAs directly modulated ridge Fabry-Perot lasers, operating at 10 Gb/s, up to 110°C, with constant current swing

Transceivers for 300 m multimode links, based on a serial 10 Gb laser source and incorporating receiver based electronic dispersion compensation (EDC) are creating the first high volume application for 10 Gb FP (Fabry Perot). A highly reliable and high yield uncooled ridge FP laser is presented. The device shows excellent power characteristics in the 25-150°C temperature range with very high T0 (95 K in the temperature range 0-85°C and still 78 K at 150°C). Outstanding dynamic performances are also shown: 6 dB of extinction ratio can be achieved up to 110°C, by using a constant current swing of 50 mA.
