Abstract :
Chip-embedded organic resonator is fabricated with 2,5-Bis(4-biphenylyl)thiophene (BP1T) crystals encapsulated with polydimethylsiloxane (PDMS). Whispering gallery mode lasing is demonstrated in these on-chip embedded crystalline microresonators, without decline in the spectral properties, and performance in comparison to the unencapsulated devices. The encapsulated lasers exhibit quality factor (Q) as high as 1066, and lasing threshold is about 120 nJ (1.5 mJ/cm2). Meanwhile, with protection of the PDMS, operation lifetime of the laser is increased from 2.1 × 106 to 4.6 × 106 pulses.
