By introducing properly designed multiple photo photon resonances (PPRs) on an active-Multimode Interferometer Laser Diode, the confirmed direct modulation bandwidth was enhanced from less than 5 GHz to at least 34 GHz. Multiple oscillating cavities that have slightly different free space ranges (FSRs) are integrated within a single device. The overlap between such FSRs contributes to multiple wavelength differences that are directly related to the PPR frequencies. Evaluated PPR frequencies from experimental data match with designed frequencies. The potential of the 100 GHz level bandwidth of the device has been proved.

Theoretical modelling of photon-photon resonance is confirmed on active MMI LD for the first time. As a result, experimentally obtained resonance peak on active MMI LD of 15GHz is explained successfully.

Active-multimode interferometer laser diode that integrates at least six oscillating cavities has been achieved successfully. Multiple cavities contribute to multiple longitudinal mode spacings as well as multiple PPR frequencies. Device aiming 100 GHz bandwidth design principle is proposed.
