Abstract: 1730nm wavelength semiconductor laser diodes(LDs) for use in medical appliances are reported.The LD structure is grown by low-pressure MOCVD,and the active region consists of five periods of InGaAs quantum wells and InGaAsP quantum barriers.The LD has a pnpn-confined buried heterojunction structure,whose ridge width and cavity length are 2μm and 300μm,respectively.After facet coating,the threshold current of the LDs is about 18±5mA at room temperature,and the operating current is about 60±5mA at an output power of 8mW.For the TO-packaged LDs,the output power is over 5mW under a 100mA operating current,and the output wavelengths are 1732±10nm.The results of high-temperature, constant-current accelerated aging show that the LDs are reliable over long operation periods and could have practical applications.
