15. Multimode spectra from a blue PQR (in red circle in Fig. 63mA/cell. 7. 5μm/step. Photonic Quantum Ring Laser of Whispering Cave Mode 31 As shown in the schematic Fig. 16, a tapered single mode fiber tip about 300nm in diameter was made by chemical etching for the photon collection, and a step motor generates relative motions of the tip against probed PQR laser device. The collected photon signal goes through single photon counting module, photon counter, and computer. Fig. 16. A schematic diagram of home-built 2D/3D single photon scanning system.
12. Spectrum of φ = 7 μm PQR laser. Fig. 13. Photometric characteristics (PQR vs LED) (a) Emission image of the 16x16 red PQR laser array (Φ= 7um, pitch = 68um). (b) Comparison of the photometric characteristics between 16x16 red PQR array and conventional high power LED. Blue GaN surface-emitting lasers are notoriously difficult to fabricate and we give a couple of recent examples of GaN surface-emitting laser work: First, a photonic crystal based surface emitting laser was developed Japanese researchers where their photonic crystal structure consists of a 2 dimensional array of airholes.
