A ring laser gyroscope without lock-in phenomenon
Satoshi Sunada, Shuichi Tamura, Keizo Inagaki +1
We theoretically and numerically study the effect of backscattering on rotating ring lasers by employing the Maxwell-Bloch equations. We show that frequency shifts due to the Sagna…
Dependence of far-field characteristics on the number of lasing modes in stadium-shaped InGaAsP microlasers
Muhan Choi, Susumu Shinohara, Takahisa Harayama
We study spectral and far-field characteristics of lasing emission from stadium-shaped semiconductor (InGaAsP) microlasers. We demonstrate that the correspondence between a lasing…
Light emission patterns from stadium-shaped semiconductor microcavity lasers
Susumu Shinohara, Takehiro Fukushima, Takahisa Harayama
We study light emission patterns from stadium-shaped semiconductor (GaAs) microcavity lasers theoretically and experimentally. Performing systematic wave calculations for passive c…
Classical Phase Space Revealed by Coherent Light
Tomoko Tanaka, Martina Hentschel, Takehiro Fukushima +1
We study the far field characteristics of oval-resonator laser diodes made of an AlGaAs/GaAs quantum well. The resonator shapes are various oval geometries, thereby probing chaotic…
Wave Chaos in Rotating Optical Cavities
Takahisa Harayama, Satoshi Sunada, Tomohiro Miyasaka
It is shown that, even when the eigenmodes of an optical cavity are wave-chaotic, the frequency splitting due to the rotation of the cavity occurs and the frequency difference is p…
Design of resonant microcavities: application to optical gyroscopes
Satoshi Sunada, Takahisa Harayama
We study theoretically and numerically the effect of rotation on resonant frequencies of microcavities in a rotating frame of reference. Cavity rotation causes the shifts of the re…
