Latest Patents

Aritake's latest patents include a light emitting element driving circuit and an optical module designed for communication devices. The light emitting element driving circuit is engineered to drive a surface-emitting element. It features a bias current driving circuit that supplies a generally constant bias current to the surface-emitting element, along with a modulation current driving circuit that superimposes a modulation current on the bias current. Additionally, it incorporates a temperature detection circuit that monitors the temperature of the surface-emitting element, adjusting the modulation current accordingly when the temperature rises. The bias current driving circuit may supply the bias current through a coil, while the modulation current driving circuit may utilize a capacitor for the modulation current.

The optical module is designed for communication forms using multimode optical fibers. It includes a surface-emitting type semiconductor laser that emits polarized light oscillating in a multimode, preferentially oriented in two given polarization axes. The optical member within the module demonstrates various functions, such as transmission, reflection, refraction, and diffraction, tailored to a predetermined polarization. This member is strategically positioned to ensure that its principal plane intersects with the emission light's traveling direction, while the polarization axis does not overlap with the emission light's polarization axes.
