  • Title: 10-Gb/s direct modulation of polymer-based tunable external cavity lasers.
    Author: Choi BS, Oh SH, Kim KS, Yoon KH, Kim HS, Park MR, Jeong JS, Kwon OK, Seo JK, Lee HK, Chung YC.
    Journal: Opt Express; 2012 Aug 27; 20(18):20368-75. PubMed ID: 23037087.
    Abstract:
    We demonstrate a directly-modulated 10-Gb/s tunable external cavity laser (ECL) fabricated by using a polymer Bragg reflector and a high-speed superluminescent diode (SLD). The tuning range and output power of this ECL are measured to be >11 nm and 2.6 mW (@ 100 mA), respectively. We directly modulate this laser at 10 Gb/s and transmit the modulated signal over 20 km of standard single-mode fiber. The power penalty is measured to be <2.8 dB at the bit-error rate (BER) of 10(-10).
