Broadband fiber-based entangled photon-pair source at telecom O-band

In this Letter, we report a polarization-entangled photon-pair source based on type-II spontaneous parametric downconversion at telecom O-band in periodically poled silica fiber (PPSF). The photon-pair source exhibits more than 130 nm (∼24 ) emission bandwidth centered at 1306.6 nm. The broad emissi...
