InAs/AlSb quantum cascade lasers emitting at 3.5-3.65 mum are demonstrated. The lasers employ a plasmon enhanced waveguide consisting of heavily doped n-InAs cladding layers and low doped InAs spacers. The maximum operation temperature is 200 and 140 K for lasers emitting near 3.65 and 3.5 mum, respectively. The present lasers' performances are limited by interband absorption in narrow gap InAs spacers
