We investigated all-optical shift register operations using 1.55-μm polarization bistable vertical-cavity surface-emitting lasers (VCSELs) formed in an array. The VCSEL array consisted of VCSELs that oscillated with single longitudinal and transvers

We observed high-frequency modulation of optical output from a short-external-cavity vertical-cavity surface-emitting laser with a new configuration. The length ${L}$ of the external cavity was reduced using a short-radius concave mirror as one end o

We demonstrate an optical header processing system using a 1.55-μm polarization bistable vertical-cavity surface-emitting laser (VCSEL) that operates as an all-optical AND gate and a holding element. Depending on the state of 1 bit in the 4-bit head

We investigated the emission wavelength dependence of the lasing polarization in a (1 1 0)-oriented vertical-cavity surface-emitting laser (VCSEL) with GaAs/AlGaAs quantum wells under optical spin injection at room temperature. Lasing was observed in
