The effect of the carrier capture into quantum wells on the modulation response of semiconductor laser is investigated. It is shown that the capture limits the maximum possible modulation speed by increasing gain nonlinearities.
An array of double-heterostructure photonic crystal QW membrane lasers was fabricated in which number of cladding periods was varied. 60 muW peak output power was collected from the facet of one device by a bare fiber.
Sapphire-bonded photonic crystal laser cavities with varying number of photonic crystal periods were studied in order to determine the optical loss in these cavities. The lasing threshold increases as the number of lattice periods decreases, and the quality factors of these cavities were calculated from the lasing threshold data. Continuous-wave operation was achieved for cavities with eight or more...
