N2 - The characteristics of the intra-cavity loss modulation laser diode (ICLM-LD) proposed in this paper were numerically and experimentally evaluated. A lower modulation sensitivity degradation rate (MSDR) of -0.30 dB/GHz and a wider 3 dB bandwidth of 49 GHz compared to those of direct modulation lasers (-0.49 dB/Hz, 16 GHz) were numerically confirmed. In addition, an MSDR of -0.29 dB/GHz and a 3 dB bandwidth wider than 30 GHz were experimentally confirmed using the fabricated ICLM-LD. The ICLM-LD will thus become a key part of ultrahigh-speed direct modulation lasers with external cavities whose modulation sensitivity is enhanced by the photon-photon resonance effect.
